21 1MRS M Section 2 RED615 overview Section 2 RED615 overview 2.1 verview RED615 is a phase-segregated two-end line differential protection and control relay designed for utility and industrial power systems, including radial, looped and meshed distribution networks with or without distributed power generation. RED615 is also designed for the protection of line differential applications with a transformer within the protection zone. RED615 relays communicate between substations over a fiber optic link or a galvanic pilot wire connection. RED615 is a member of ABB s Relion product family and part of its 615 protection and control product series. The 615 series relays are characterized by their compactness and withdrawable-unit design. Reengineered from the ground up, the 615 series has been guided by the IEC standard for communication and interoperability of substation automation equipment. The relay provides unit type main protection for overhead lines and cable feeders in distribution networks. The relay also features current-based protection functions for remote back-up for down-stream protection relays and local back-up for the line differential main protection. Further, standard configurations B and C also include earth-fault protection. Standard configurations D and E include directional overcurrent and voltage based protection functions. The relay is adapted for the protection of overhead line and cable feeders in isolated neutral, resistance earthed, compensated (impedance earthed) and solidly earthed networks. nce the relay has been given the application-specific settings, it can directly be put into service. The 615 series relays support a range of communication protocols including IEC with Edition 2 support, process bus according to IEC LE, IEC , Modbus and DNP3. Profibus DPV1 communication protocol is supported by using the protocol converter SPA-ZC 302. RED615 15

The default passwords in the protection relay delivered from the factory can be changed with Administrator user rights. User authorization is disabled by default for LHMI but WHMI always uses authorization.

Critical system and protection relay security-related events are logged to a separate nonvolatile audit trail for the administrator. Audit trail is a chronological record of system activities that allows the reconstruction and examination of the sequence of system and security-related events and changes in the protection relay. Both audit trail events and process related events can be examined and analyzed in a consistent method with the help of Event List in LHMI and WHMI and Event Viewer in PCM RED615

31 1MRS M Section 2 RED615 overview The protection relay stores 2048 audit trail events to the nonvolatile audit trail. Additionally, 1024 process events are stored in a nonvolatile event list. Both the audit trail and event list work according to the FIF principle. Nonvolatile memory is based on a memory type which does not need battery backup nor regular component change to maintain the memory storage. Audit trail events related to user authorization (login, logout, violation remote and violation local) are defined according to the selected set of requirements from IEEE The logging is based on predefined user names or user categories. The user audit trail events are accessible with IEC , PCM600, LHMI and WHMI.

Profibus DPV1 26 RED615

33 1MRS M Section 2 RED615 overview communication protocol is supported by using the protocol converter SPA-ZC 302. perational information and controls are available through these protocols. However, some communication functionality, for example, horizontal communication between the protection relays, is only enabled by the IEC communication protocol. The IEC communication implementation supports all monitoring and control functions. Additionally, parameter settings, disturbance recordings and fault records can be accessed using the IEC protocol. Disturbance recordings are available to any Ethernet-based application in the IEC standard CMTRADE file format. The protection relay can send and receive binary signals from other devices (so-called horizontal communication) using the IEC GSE profile, where the highest performance class with a total transmission time of 3 ms is supported. Furthermore, the protection relay supports sending and receiving of analog values using GSE messaging. The protection relay meets the GSE performance requirements for tripping applications in distribution substations, as defined by the IEC standard. The protection relay can support five simultaneous clients. If PCM600 reserves one client connection, only four client connections are left, for example, for IEC and Modbus. All communication connectors, except for the front port connector, are placed on integrated optional communication modules. The protection relay can be connected to Ethernet-based communication systems via the RJ-45 connector (100Base-TX) or the fiber-optic LC connector (100Base-FX). An optional serial interface is available for RS-232/RS-485 communication Self-healing Ethernet ring For the correct operation of self-healing loop topology, it is essential that the external switches in the network support the RSTP protocol and that it is enabled in the switches. therwise, connecting the loop topology can cause problems to the network. The protection relay itself does not support link-down detection or RSTP. The ring recovery process is based on the aging of the MAC addresses, and the linkup/link-down events can cause temporary breaks in communication. For a better performance of the self-healing loop, it is recommended that the external switch furthest from the protection relay loop is assigned as the root switch (bridge priority = 0) and the bridge priority increases towards the protection relay loop. The end links of the protection relay loop can be attached to the same external switch or to two adjacent external switches. A self-healing Ethernet ring requires a communication module with at least two Ethernet interfaces for all protection relays. RED615 27

If more than 30 protection relays are to be connected, it is recommended that the network is split into several rings with no more than 30 protection relays per ring. Each protection relay has a 50-μs store-and-forward delay, and to fulfil the performance requirements for fast horizontal communication, the ring size is limited to 30 protection relays Ethernet redundancy IEC specifies a network redundancy scheme that improves the system availability for substation communication. It is based on two complementary protocols defined in the IEC :2012 standard: parallel redundancy protocol PRP-1 and high-availability seamless redundancy HSR protocol. Both protocols rely on the duplication of all transmitted information via two Ethernet ports for one logical network connection. Therefore, both are able to overcome the failure of a link or switch with a zero-switchover time, thus fulfilling the stringent real-time requirements for the substation automation horizontal communication and time synchronization. PRP specifies that each device is connected in parallel to two local area networks. HSR applies the PRP principle to rings and to the rings of rings to achieve costeffective redundancy. Thus, each device incorporates a switch element that forwards frames from port to port. The HSR/PRP option is available for all 615 series protection relays. However, RED615 supports this option only over fiber optics. 28 RED615

35 1MRS M Section 2 RED615 overview IEC :2012 cancels and replaces the first edition published in These standard versions are also referred to as IEC Edition 1 and IEC Edition 2. The protection relay supports IEC :2012 and it is not compatible with IEC :2010. PRP Each PRP node, called a doubly attached node with PRP (DAN), is attached to two independent LANs operated in parallel. These parallel networks in PRP are called LAN A and LAN B. The networks are completely separated to ensure failure independence, and they can have different topologies. Both networks operate in parallel, thus providing zero-time recovery and continuous checking of redundancy to avoid communication failures. Non-PRP nodes, called single attached nodes (SANs), are either attached to one network only (and can therefore communicate only with DANs and SANs attached to the same network), or are attached through a redundancy box, a device that behaves like a DAN. CM600 SCADA Ethernet switch IEC PRP Ethernet switch REF615 REF620 RET620 REM620 REF615 GUID-334D26-C3BD-47-BD9D A5E9D V1 EN Figure 7: PRP solution In case a laptop or a PC workstation is connected as a non-prp node to one of the PRP networks, LAN A or LAN B, it is recommended to use a redundancy box device or an Ethernet switch with similar functionality between the PRP network and SAN to remove additional PRP information from the Ethernet frames. In some cases, default PC workstation adapters are not able to handle the maximum-length Ethernet frames with the PRP trailer. There are different alternative ways to connect a laptop or a workstation as SAN to a PRP network. RED615 29

36 Section 2 RED615 overview 1MRS M Via an external redundancy box (RedBox) or a switch capable of connecting to PRP and normal networks By connecting the node directly to LAN A or LAN B as SAN By connecting the node to the protection relay's interlink port HSR HSR applies the PRP principle of parallel operation to a single ring, treating the two directions as two virtual LANs. For each frame sent, a node, DAN, sends two frames, one over each port. Both frames circulate in opposite directions over the ring and each node forwards the frames it receives, from one port to the other. When the originating node receives a frame sent to itself, it discards that to avoid loops; therefore, no ring protocol is needed. Individually attached nodes, SANs, such as laptops and printers, must be attached through a redundancy box that acts as a ring element. For example, a 615 or 620 series protection relay with HSR support can be used as a redundancy box. GUID A7-3AEC-42-BC4D V1 EN Figure 8: HSR solution Process bus Process bus IEC defines the transmission of Sampled Measured Values within the substation automation system. International Users Group created a guideline IEC LE that defines an application profile of IEC to facilitate implementation and enable interoperability. Process bus is used for distributing process data from the primary circuit to all process bus compatible IEDs in the local network in a real-time manner. The data can then be processed by any IED to perform different protection, automation and control functions. 30 RED615

37 GSE SMV GSE SMV GSE SMV GSE SMV GSE SMV GSE SMV GSE SMV 1MRS M Section 2 RED615 overview UniGear Digital switchgear concept relies on the process bus together with current and voltage sensors. The process bus enables several advantages for the UniGear Digital like simplicity with reduced wiring, flexibility with data availability to all IEDs, improved diagnostics and longer maintenance cycles. With process bus the galvanic interpanel wiring for sharing busbar voltage value can be replaced with Ethernet communication. Transmitting measurement samples over process bus brings also higher error detection because the signal transmission is automatically supervised. Additional contribution to the higher availability is the possibility to use redundant Ethernet network for transmitting SMV signals. Common Ethernet Station bus (IEC ), process bus (IEC LE) and IEEE 1588 v2 time synchronization GUID-2371EFA F1A-A23F-CF0CE2D474D3 V4 EN Figure 9: Process bus application of voltage sharing and synchrocheck The 615 series supports IEC process bus with sampled values of analog currents and voltages. The measured values are transferred as sampled values using the IEC LE protocol which uses the same physical Ethernet network as the IEC station bus. The intended application for sampled values is sharing the measured voltages from one 615 series IED to other IEDs with phase voltage based functions and 9-2 support. The 615 series IEDs with process bus based applications use IEEE 1588 v2 Precision Time Protocol (PTP) according to IEEE C Power Profile for high accuracy time synchronization. With IEEE 1588 v2, the cabling infrastructure requirement is reduced by allowing time synchronization information to be transported over the same Ethernet network as the data communications.

Another requirement is a communication card with IEEE 1588 v2 support (CM CM0037). However, RED615 supports this option only with the communication card variant having fiber optic station bus ports. See the IEC engineering guide for detailed system requirements and configuration details Secure communication The protection relay supports secure communication for WHMI and file transfer protocol. If the Secure Communication parameter is activated, protocols require TLS based encryption method support from the clients. In this case WHMI must be connected from a Web browser using the HTTPS protocol and in case of file transfer the client must use FTPS Protection communication and supervision The communication between the relays is enabled by means of a dedicated fiber optic communication channel nm multi-mode or single-mode fibers with LC connectors are used for line differential communication. The channel is used for transferring the phase segregated current value data between the relays. The current phasors from the two relays, geographically located apart from each other, must be time coordinated so that the current differential algorithm can be executed correctly. The so called echo method is used for time synchronization. No external devices such as GPS clocks are thereby needed for the line differential protection communication. 32 RED615

39 1MRS M Section 2 RED615 overview Apart from the continued protection communication, the communication channel can also be used for binary signal transfer (BST) that is, transferring of user configurable binary information between the relays. There are a total of eight BST signals available for user definable purposes. The BST signals can originate from the relay s binary inputs or internal logics, and be assigned to the remote relay s binary outputs or internal logics. The protection communication supervision continuously monitors the protection communication link. The relay immediately blocks the line differential protection function in case that severe interference in the communication link, risking the correct operation of the function, is detected. An alarm signal will eventually be issued if the interference, indicating permanent failure in the protection communication, persists. The two high-set stages of the overcurrent protection are further by default released.

41 1MRS M Section 3 Section Standard configurations RED615 is available in five alternative standard configurations. The standard signal configuration can be altered by means of the signal matrix or the graphical application functionality of the Protection and Control IED Manager PCM600. Further, the application configuration functionality of PCM600 supports the creation of multilayer logic functions utilizing various logical elements including timers and flip-flops. By combining protection functions with logic function blocks the relay configuration can be adapted to user specific application requirements. The relay is delivered from the factory with default connections described in the functional diagrams for binary inputs, binary outputs, function-to-function connections and alarm LEDs. Some of the supported functions in RED615 must be added with the Application Configuration tool to be available in the Signal Matrix tool and in the relay. The positive measuring direction of directional protection functions is towards the outgoing feeder.

The integration enables releasing some initially reserved binary inputs and outputs of the IED s standard configuration. The suitability of the IED s binary outputs which have been selected for primary device control should be carefully verified, for example make and carry and breaking capacity. If the requirements for the primary device control circuit are not met, using external auxiliary relays should be considered. 38 RED615

The default connections can be viewed and changed with PCM600 according to the application requirements. The analog channels have fixed connections to the different function blocks inside the IED s standard configuration. However, the 12 analog channels available for the disturbance recorder function are freely selectable as a part of the disturbance recorder s parameter settings. The phase currents to the IED are fed from a current transformer. The residual current to the IED is fed from either residually connected CTs, an external core balance CT, neutral CT or internally calculated. The IED offers six different settings group which can be set based on individual needs. Each group can be activated or deactivated using the setting group settings available in the IED or via binary input. Depending on the communication protocol the required function block needs to be instantiated in the configuration Functional diagrams for protection The functional diagrams describe the IED's protection functionality in detail and according to the factory set default connections. The line differential protection with in-zone power transformer LNPLDF1 is intended to be the main protection offering exclusive unit protection for the power distribution lines or cables. The stabilized low stage can be blocked if the current transformer failure is detected. The operate value of the instantaneous high stage can be multiplied by predefined settings, if ENA_MULT_HS input is activated. In this configuration, it is activated by the open status information of the remote-end circuit breaker and earthswitch, and if the disconnector is not in the intermediate position. The intention of this connection is to lower the setting value of the instantaneous high stage by multiplying with the setting High p value Mult, in case of internal fault. Alarm LED3 informs when the line differential is not available possibly due to a failure in protection communication, or if the function is set in a test mode. RED615 47

The analog channels have fixed connections to the different function blocks inside the IED s standard configuration. However, the 12 analog channels available for the disturbance recorder function are freely selectable as a part of the disturbance recorder s parameter settings. The phase currents to the IED are fed from a current transformer. The residual current to the IED is fed from either residually connected CTs, an external core balance CT, neutral CT or internally calculated. The residual voltage to the IED is fed from either residually connected VTs or an open delta connected VT. The IED offers six different settings group which can be set based on individual needs. Each group can be activated or deactivated using the setting group settings available in the IED or via binary input. Depending on the communication protocol the required function block needs to be instantiated in the configuration Functional diagrams for protection The functional diagrams describe the IED's protection functionality in detail and according to the factory set default connections. Line differential protection with in-zone power transformer LNPLDF1 is intended to be the main protection offering exclusive unit protection for the power distribution lines or cables. The stabilized low stage can be blocked if the current transformer failure is detected. The operate value of the instantaneous high stage can be multiplied by predefined settings if the ENA_MULT_HS input is activated. In this configuration, the input is activated by the open status information of the remote-end circuit breaker and earth-switch, and if the disconnector is not in the intermediate state. The intention of this connection is to lower the setting value of the instantaneous high stage by multiplying with setting High p value Mult, in case of internal fault. 66 RED615

Four non-directional overcurrent stages are offered for overcurrent and short-circuit protection. The three-phase non-directional overcurrent protection, instantaneous stage PHIPTC1 can be blocked by energizing the binary input X120: BI1.

The default connections can be viewed and changed with PCM600 according to the application requirements. The analog channels have fixed connections to the different function blocks inside the IED s standard configuration. However, the 12 analog channels available for the disturbance recorder function are freely selectable as a part of the disturbance recorder s parameter settings. The phase currents to the IED are fed from a current transformer. The residual current to the IED is fed from either residually connected CTs, an external core balance CT, neutral CT or internally calculated. 92 RED615

99 1MRS M Section 3 RED615 offers six different settings group which can be set based on individual needs. Each group can be activated or deactivated using the setting group settings available in RED615. Depending on the communication protocol the required function block needs to be instantiated in the configuration Functional diagrams for protection The functional diagrams describe the IED's protection functionality in detail and according to the factory set default connections. Line differential protection with in-zone power transformer LNPLDF1 is intended to be the main protection offering exclusive unit protection for the power distribution lines or cables. The stabilized low stage can be blocked if the current transformer failure is detected. The operate value of the instantaneous high stage can be multiplied by predefined settings if the ENA_MULT_HS input is activated. In this configuration it is activated by the open status information of the remote-end circuit breaker and earth switch, and if the disconnector is not in the intermediate state. The intention of this connection is to lower the setting value of the instantaneous high stage by multiplying with setting High p value Mult, in case of internal fault. Alarm LED3 informs when the line differential is not available possibly due to a failure in protection communication, or if the function is set in a test mode. Four non-directional overcurrent stages are offered for overcurrent and short-circuit protection. Three-phase non-directional overcurrent protection, instantaneous stage, PHIPTC1 can be blocked by energizing the binary input X120:BI1. The instantaneous and first high stages are blocked by activation of line differential protection. RED615 93

The standard configuration for line current differential protection includes support for in-zone transformers. The configuration also includes additional options to select earth-fault protection based on admittance, wattmetric or harmonic principle. Standard configuration D is not designed for using all the available functionality content in one relay at the same time. Frequency protection functions and third instances of voltage protection functions must be added with the Application Configuration tool. To ensure the performance of the relay, the user-specific configuration load is verified with the Application Configuration tool in PCM600. The IED with a standard configuration is delivered from the factory with default settings and parameters. The end user flexibility for incoming, outgoing and internal signal designation within the IED enables this configuration to be further adapted to different primary circuit layouts and the related functionality needs by modifying the internal functionality using PCM600.

The default connections can be viewed and changed with PCM600 according to the application requirements. The analog channels have fixed connections to the different function blocks inside the IED s standard configuration. However, the 12 analog channels available for the disturbance recorder function are freely selectable as a part of the disturbance recorder s parameter settings. The phase currents to the IED are fed from a current transformer. The residual current to the IED is fed from either residually connected CTs, an external core balance CT, neutral CT or internally calculated. 116 RED615

123 1MRS M Section 3 The phase voltages to the IED are fed from a voltage transformer. The residual voltage to the IED is fed from either residually connected VTs, an open delta connected VT or internally calculated. RED615 offers six different settings group which can be set based on individual needs. Each group can be activated or deactivated using the setting group settings available in RED615. Depending on the communication protocol the required function block needs to be instantiated in the configuration Functional diagrams for protection The functional diagrams describe the IEDs protection functionality in detail and according to the factory set default connections. Line differential protection with in-zone power transformer LNPLDF1 is intended to be the main protection offering exclusive unit protection for the power distribution lines or cables. The stabilized low stage can be blocked if the current transformer failure is detected. The operate value of the instantaneous high stage can be multiplied by predefined settings if the ENA_MULT_HS input is activated. In this configuration, it is activated by the open status information of the remote-end circuit breaker and earth switch, and if the disconnector is not in the intermediate state. The intention of this connection is to lower the setting value of the instantaneous high stage by multiplying with setting High p value Mult, in case of internal fault. Alarm LED3 informs when the line differential is not available possibly due to a failure in protection communication, or if the function is set in a test mode. RED

The default connections can be viewed and changed with PCM600 according to the application requirements. The analog channels have fixed connections to the different function blocks inside the IED s standard configuration. However, the 12 analog channels available for the disturbance recorder function are freely selectable as a part of the disturbance recorder s parameter settings. The phase currents to the IED are fed from Rogowski or Combi sensors. The residual current to the IED is fed from either residually connected CTs, an external core balance CT, neutral CT or internally calculated. The phase voltages to the IED are fed from Combi sensors. The residual voltage is calculated internally. RED615 offers six different settings group which can be set based on individual needs. Each group can be activated or deactivated using the setting group settings available in RED615. Depending on the communication protocol the required function block needs to be instantiated in the configuration. RED

154 Section 3 1MRS M Functional diagrams for protection The functional diagrams describe the IEDs protection functionality in detail and according to the factory set default connections. Line differential protection with in-zone power transformer LNPLDF1 is intended to be the main protection offering exclusive unit protection for the power distribution lines or cables. The stabilized low stage can be blocked if the current transformer failure is detected. The operate value of the instantaneous high stage can be multiplied by predefined settings if the ENA_MULT_HS input is activated. In this configuration, it is activated by the open status information of the remote-end circuit breaker and earth switch, and if the disconnector is not in the intermediate state. The intention of this connection is to lower the setting value of the instantaneous high stage by multiplying with setting High p value Mult, in case of internal fault.

177 1MRS M Section 4 Requirements for measurement transformers Section 4 Requirements for measurement transformers 4.1 Current transformers Current transformer requirements for non-directional overcurrent protection For reliable and correct operation of the overcurrent protection, the CT has to be chosen carefully. The distortion of the secondary current of a saturated CT may endanger the operation, selectivity, and co-ordination of protection. However, when the CT is correctly selected, a fast and reliable short circuit protection can be enabled. The selection of a CT depends not only on the CT specifications but also on the network fault current magnitude, desired protection objectives, and the actual CT burden. The protection settings of the protection relay should be defined in accordance with the CT performance as well as other factors Current transformer accuracy class and accuracy limit factor The rated accuracy limit factor (F n ) is the ratio of the rated accuracy limit primary current to the rated primary current. For example, a protective current transformer of type 5P10 has the accuracy class 5P and the accuracy limit factor 10. For protective current transformers, the accuracy class is designed by the highest permissible percentage composite error at the rated accuracy limit primary current prescribed for the accuracy class concerned, followed by the letter "P" (meaning protection). Table 36: Limits of errors according to IEC for protective current transformers Accuracy class Current error at rated primary current (%) Phase displacement at rated primary current minutes centiradians 5P ±1 ±60 ± P ± Composite error at rated accuracy limit primary current (%) The accuracy classes 5P and 10P are both suitable for non-directional overcurrent protection. The 5P class provides a better accuracy. This should be noted also if there are accuracy requirements for the metering functions (current metering, power metering, and so on) of the protection relay. The CT accuracy primary limit current describes the highest fault current magnitude at which the CT fulfils the specified accuracy. Beyond this level, the secondary current RED

178 Section 4 Requirements for measurement transformers 1MRS M of the CT is distorted and it might have severe effects on the performance of the protection relay. In practise, the actual accuracy limit factor (F a ) differs from the rated accuracy limit factor (F n ) and is proportional to the ratio of the rated CT burden and the actual CT burden. The actual accuracy limit factor is calculated using the formula: F a S Fn S A V1 EN in in + S n + S F n S in S the accuracy limit factor with the nominal external burden S n the internal secondary burden of the CT the actual external burden Non-directional overcurrent protection The current transformer selection Non-directional overcurrent protection does not set high requirements on the accuracy class or on the actual accuracy limit factor (F a ) of the CTs. It is, however, recommended to select a CT with F a of at least 20. The nominal primary current I 1n should be chosen in such a way that the thermal and dynamic strength of the current measuring input of the protection relay is not exceeded. This is always fulfilled when I 1n > I kmax / 100, I kmax is the highest fault current. The saturation of the CT protects the measuring circuit and the current input of the protection relay. For that reason, in practice, even a few times smaller nominal primary current can be used than given by the formula. Recommended start current settings If I kmin is the lowest primary current at which the highest set overcurrent stage is to operate, the start current should be set using the formula: Current start value < 0.7 (I kmin / I 1n ) I 1n is the nominal primary current of the CT. The factor 0.7 takes into account the protection relay inaccuracy, current transformer errors, and imperfections of the short circuit calculations. 172 RED615

179 1MRS M Section 4 Requirements for measurement transformers The adequate performance of the CT should be checked when the setting of the high set stage overcurrent protection is defined. The operate time delay caused by the CT saturation is typically small enough when the overcurrent setting is noticeably lower than F a. When defining the setting values for the low set stages, the saturation of the CT does not need to be taken into account and the start current setting is simply according to the formula. Delay in operation caused by saturation of current transformers The saturation of CT may cause a delayed protection relay operation. To ensure the time selectivity, the delay must be taken into account when setting the operate times of successive protection relays. With definite time mode of operation, the saturation of CT may cause a delay that is as long as the time the constant of the DC component of the fault current, when the current is only slightly higher than the starting current. This depends on the accuracy limit factor of the CT, on the remanence flux of the core of the CT, and on the operate time setting. With inverse time mode of operation, the delay should always be considered as being as long as the time constant of the DC component. With inverse time mode of operation and when the high-set stages are not used, the AC component of the fault current should not saturate the CT less than 20 times the starting current. therwise, the inverse operation time can be further prolonged. Therefore, the accuracy limit factor F a should be chosen using the formula: F a > 20 Current start value / I 1n The Current start value is the primary start current setting of the protection relay Example for non-directional overcurrent protection The following figure describes a typical medium voltage feeder. The protection is implemented as three-stage definite time non-directional overcurrent protection. RED

180 Section 4 Requirements for measurement transformers 1MRS M A V1 EN Figure 251: Example of three-stage overcurrent protection The maximum three-phase fault current is 41.7 ka and the minimum three-phase short circuit current is 22.8 ka. The actual accuracy limit factor of the CT is calculated to be 59. The start current setting for low-set stage (3I>) is selected to be about twice the nominal current of the cable. The operate time is selected so that it is selective with the next protection relay (not visible in Figure 251). The settings for the high-set stage and instantaneous stage are defined also so that grading is ensured with the downstream protection. In addition, the start current settings have to be defined so that the protection relay operates with the minimum fault current and it does not operate with the maximum load current. The settings for all three stages are as in Figure 251. For the application point of view, the suitable setting for instantaneous stage (I>>>) in this example is A (5.83 I 2n ). For the CT characteristics point of view, the criteria given by the current transformer selection formula is fulfilled and also the protection relay setting is considerably below the F a. In this application, the CT rated burden could have been selected much lower than 10 VA for economical reasons. 174 RED615

187 1MRS M Section 5 IED physical connections IRF The IRF contact functions as an output contact for the self-supervision system of the protection relay. Under normal operating conditions, the protection relay is energized and the contact is closed (X100:3-5). When a fault is detected by the self-supervision system or the auxiliary voltage is disconnected, the output contact drops off and the contact closes (X100:3-4). Table 55: IRF contact Terminal Description X100:3 IRF, common X100:4 Closed; IRF, or U aux disconnected X100:5 Closed; no IRF, and U aux connected 5.3 Protection communication options Two different protection communication options are available for the IED, that is, a fiber optic link and a galvanic pilot wire link. Multi-mode or single-mode glass fiber can be used in a fiber optic link. Select the required glass fiber mode when ordering the IED. Link lengths up to 2 km with multimode fiber and link lengths up to 20 km with single-mode fiber can be achieved. The fiber optic cable used for protection communication is connected to the X16/LD connector in the IED. See the technical manual for more information. If a galvanic pilot wire is used as a protection communication link, the pilot wire modem RPW600 is required. Select the pilot wire option when ordering the IED. The protection communication link always requires two modems in a protection scheme, thus delivered in pairs of master (RPW600M) and follower (RPW600F) units. The IED is connected to the pilot wire modem using a single-mode fiber optic cable. Thus a single-mode version of IED is required if the pilot wire link is used. The fiber optic cable is connected to the X16/LD connector in the IED and in Ethernet FX connector in the pilot wire modem. Setting or configuration is not needed with either of the pilot wire modem variants or with the IED. Pilot wire link lengths up to 8 km with 0.8 mm 2 twisted pair cables can be applied. Even higher distances can be achieved with good quality twisted pair cables in the pilot wire link. The achieved link length also depends on the noise levels in the installations. The pilot wire modem has QoS (quality of service) LEDs in the front panel for easy diagnostics of the pilot wire link quality. The diagnostics feature does not depend on the payload over the pilot wire link and can be used for checking the quality of the intended pilot wire link even without installing the IEDs. In addition, a diagnostic kit is available as an ordering option for more advanced diagnostic and logging of diagnostic parameters of the pilot wire link. The kit consists of a CD-RM with the RED
