38 Chapter 3 Installing IED rear of the IED. Procedure: 1. Connect signals to the female connector All wiring to the female connector should be done before it is plugged into the male part and screwed to the case. The conductors can be of rigid type (solid, stranded) or of flexible type. The female connectors accept conductors with a cross section area of mm 2 (AWG 24-15). If two conductors are used in the same terminal, the maximum permissible cross section area is mm 2 (AWG 24-18, each conductor corresponding to one cross section area). If two conductors, each with area 1.5 mm 2 (AWG 15) need to be connected to the same terminal, a ferrule must be used to combine the two conductors, no soldering is needed. Press the locking button by screwdriver to insert the wiring with ferrule into the connector, move away the screwdriver after the ferrule has been inserted into the connector completely to lock the wiring tightly.

Lock the connector by fastening the lock screws 3.6 Making the screen connection When using screened cables always make sure screens are earthed and connected according to applicable engineering methods. This may include checking for appropriate earth points near the IED, for instance, in the cubicle and/or near the source of measuring. Ensure that earth connections are made with short conductors of an adequate cross section, at least 6 mm 2 (AWG10) for single screen connections. 3.7 Optical connections This port is used to transmit the binary data between IEDs, there are two optical ports at the rear side of CPU moduel, Figure 9 and Figure 10, the two ports works in redundancy communication mode. 28

40 Chapter 3 Installing IED The fiber optical cables are very sensitive to handling. Do not bend too sharply. If cable straps are used to fix the cables, apply with loose fit. Always hold the connector, never the cable, when connecting or disconnecting optical fibers. Do not twist, pull or bend the fiber. Invisible damage may increase fiber attenuation thus making communication impossible. Strictly follow the instructions from manufacture for each type of optical cables or connectors. 3.8 RS485 and RS232 ports connection RS485 port connection The RS485 interface is capable of half-duplex service with the signals A/A' and B/B' to transmit signals. The network topology of RS485 adopts bus type of terminal matched, do not support ring or star network. Use the single and continuous channel as bus. The terminating resistance is located on beginning and terminal of the bus cable. The other ports do not need the terminating resistance. As shown in Figure 7 and Figure 8, RS485 port located on the rear side of communication module. The IED provides two electrical isolation RS485 ports, the two ports can work at the same time with IEC protocol supported RS232 port connection One RS232 serial port is provided and located on front plate, which is used to connect personal computer. The RS232 port adopts half-dupex communication mode, usually which is connected with 9-pin D-subminiature female connectors Connection method: direction connection cable for serial port, the IED terminal is pins and the PC termianl is female connector. The terminal of 2, 3, 4 and 5 is connected directly. As shown in the following picture: 29

41 Chapter 3 Installing IED Figure 14 Example for serial port connection The line 4 must be connected directly 3.9 Connecting the GPS Mount the GPS antenna on the building roof or the place of visibility to all direction is obtained, top of the antenna should be horizontal. Mount the antenna to console and fix the console on the building roof with expansion bolts. The turning radius should not be too small when laying the cables. The length of antenna cables is designed strictly based on antenna gain, so, it is not allowed to lengthen, shorten or add connectors that will affect signal reception or can't receive any signals. The principle for mounting GPS antenna is that the position is visible completely to all directions in 360, however, for some special conditions, mount the antenna at the place with best visibility as far as possible. The GPS port is located on the rear side of communication module, as shown in Figure 7 and Figure 8, which can be connected with screened twist-pair cable. 30

42 4 Checking before energizing 4.1 Introduction Chapter 3 Installing IED After completing the IED connections, the related connections need to be checked, this section descirbes what should be checked before energizing. This is done with IED and all connected circuits de-energized. 4.2 Checking the protective earth connection Check the protective earthing connection of IED is connected reliably in accordance with the related electrical regulations and standards. 4.3 Checking the power supply connection Check that the auxiliary power supply voltage remains within the permissible input voltage range under all operating conditions. Check that the polarity is correct. 4.4 Checking the CT and VT circuits connection Checking the CT circuits connection Check that the wiring is in strict accordance with the supplied connection diagram. If any errors appearance, do not continue before any errors are corrected. The following tests shall be performed on every primary CT connected to IED: Primary injection test to verify the current change ratio of the CT, the correct wiring up to the protection IED and correct phase sequence connection (i.e. A, B, C) Polarity checking to prove that the predicted direction of secondary current flow is correct for a given direction of primary current flow CT secondary loop resistance measurement in order to confirm that the current transformer secondary loop DC resistance is within specification and that there are no high resistance joints in the CT winding or wiring 31

43 Chapter 3 Installing IED CT excitation test in order to confirm that the current transformer is of the correct accuracy rating and that there are no shorted turns in the current transformer windings. Manufacturer's design curves should be available for the current transformer in order to compare the actual results Check the earthing of the individual CT secondary circuits to verify that each three-phase set of main CTs is properly connected to the station earth and only at one electrical point Checking the insulation resistance Phase identification of CT shall be made Both primary and secondary sides must be disconnected from the line and IED when plotting the excitation characteristics If the CT secondary circuit earth connection is removed without the current transformer primary being de-energized, dangerous voltages may result in the secondary CT circuits Checking the VT connection Check that the wiring is in strict accordance with the supplied connection diagram. If any errors appearance, do not continue before any errors are corrected. The following tests are recommended: Polarity check VT circuit voltage measurement (primary injection test) Grounding check Phase relationship Insulation resistance check 4.5 Checking the binary input and output connection Checking the binary input connection 32

44 Chapter 3 Installing IED When checking the binary inputs, it's better to disconnect the binary input connector from binary input module. Check all connected signals in order to make sure that both the input level and polarity of voltage are in accordance with the IEDs specifications Checking the binary output connection When checking the binary outputs, it's better to disconnect the binary output connector from binary output module. Check all connected signals in order to make sure that both the input level and polarity of voltage are in accordance with the IEDs specifications. 4.6 Checking the screened cables connection Check that the screened cables are connected correctly. 4.7 Checking the optical connections Check that the Tx and Rx optical connections are correct. 4.8 Checking the S485 and RS232 port connectios Checking the RS485 port connection Check that the RS485 port connections are correct Checking RS232 port connection Check that the RS232 serial port connections are correct. 4.9 Checking GPS connection Check that the GPS connections are correct Checking the insulation voltage and insulation resistance 33
