35 4 Packaging, transport and storage Packaging, transport and storage Packaging Suitability, structure and production The goods are packaged in a sturdy cardboard box. This ensures that the shipment is secure when in the intended transportation position and that none of its parts touch the loading surface of the means of transport or touch the ground after unloading. The box is designed for a maximum load of 10 kg. Inlays inside the box stabilize the goods, preventing impermissible changes of position, and protect them from vibration Markings The packaging bears a signature with instructions for safe transport and correct storage. The following symbols apply to the shipment of non-hazardous goods. Adherence to these symbols is mandatory. Protect against moisture Table 6: Shipping pictograms Top Fragile Attach lifting gear here Center of mass 4.2 Transportation, receipt and handling of shipments In addition to oscillation stress and shock stress, jolts must also be expected during transportation. In order to prevent possible damage, avoid dropping, tipping, knocking over and colliding with the product. If a crate tips over, falls from a certain height (e.g. when slings tear) or experiences an unbroken fall, damage must be expected regardless of the weight. Every delivered shipment must be checked for the following by the recipient before acceptance (acknowledgment of receipt): Completeness based on the delivery slip External damage of any type. The checks must take place after unloading when the crate or transport container can be accessed from all sides. Maschinenfabrik Reinhausen /04 EN TRAFOGUARD 35

36 4 Packaging, transport and storage Visible damage Hidden damage If external transport damage is detected on receipt of the shipment, proceed as follows: Immediately record the transport damage found in the shipping documents and have this countersigned by the carrier. In the event of severe damage, total loss or high damage costs, immediately notify the sales department at Maschinenfabrik Reinhausen and the relevant insurance company. After identifying damage, do not modify the condition of the shipment further and retain the packaging material until an inspection decision has been made by the transport company or the insurance company. Record the details of the damage immediately onsite together with the carrier involved. This is essential for any claim for damages! If possible, photograph damage to packaging and packaged goods. This also applies to signs of corrosion on the packaged goods due to moisture inside the packaging (rain, snow, condensation). Be absolutely sure to also check the sealed packaging. When damages are not determined until unpacking after receipt of the shipment (hidden damage), proceed as follows: Make the party responsible for the damage liable as soon as possible by telephone and in writing, and prepare a damage report. Observe the time periods applicable to such actions in the respective country. Inquire about these in good time. With hidden damage, it is very hard to make the transportation company (or other responsible party) liable. Any insurance claims for such damages can only be successful if relevant provisions are expressly included in the insurance terms and conditions. 4.3 Storage of shipments When selecting and setting up the storage location, ensure the following: Protect stored goods against moisture (flooding, water from melting snow and ice), dirt, pests such as rats, mice, termites and so on, and against unauthorized access. Store the crates on timber beams and planks as a protection against rising damp and for better ventilation. Ensure sufficient carrying capacity of the ground. Keep entrance paths free. Check stored goods at regular intervals. Also take appropriate action after storms, heavy rain or snow and so on. 36 TRAFOGUARD /04 EN Maschinenfabrik Reinhausen 2014

40 5 Mounting Information about laying fiber-optic cable To ensure the smooth transfer of data via the fiber-optic cable, you must ensure that mechanical loads are avoided when laying the fiber-optic cable and later on during operation. Please note the following: Radii must not fall below the minimum permissible bend radii (do not bend fiber-optic cable). The fiber-optic cables must not be over-stretched or crushed. Observe the permissible load values. The fiber-optic cables must not be twisted. Be aware of sharp edges which could damage the fiber-optic cable's coating when laying or could place mechanical loading on the coating later on. Provide a sufficient cable reserve near distributor cabinets for example. Lay the reserve such that the fiber-optic cable is neither bent nor twisted when tightened Electromagnetic compatibility The device has been developed in accordance with applicable EMC standards. The following points must be noted in order to maintain the EMC standards Wiring requirement of installation site Note the following when selecting the installation site: The system's overvoltage protection must be effective. The system's ground connection must comply with all technical regulations. Separate system parts must be joined by a potential equalization.

71 8 Functions and settings Monitoring contact wear When monitoring the OILTAP type on-load tap-changers, the monitoring system calculates the following values after each operation: Switching contact wear (SKA) Resistance contact wear (WKA) Oil soot If the parameter "Trial tap-change operation" is activated, no wear and no soot is calculated. This parameter serves to prevent falsification of the wear and soot values during commissioning or transformer tests. The monitoring system checks the calculated values with regard to the following limit values: Absolute value of the wear Difference in wear between main switching contact and transition contact Difference in wear between two transition contacts If these limit values are exceeded, the monitoring system triggers appropriate events. After maintenance work on the on-load tap-changer, the computed wear of the main switch contacts and the transition contacts have to be entered into the monitoring system. The monitoring system adapts its calculation model automatically using the computed wear. By doing so, future calculations of the wear will be even more precise Cooling system control You can use the "Cooling system control" function package to control up to 6 cooling stages in a cooling system. You can also monitor the inlet and outlet temperature of the cooling medium in each cooling stage. Function The monitoring system monitors the following temperatures to control the cooling system: Topoil temperature: Oil temperature at top of transformer (measured value) Hotspot temperature (winding temperature): Highest temperature on the transformer winding (calculated value) The hotspot temperature is calculated in accordance with IEC : Maschinenfabrik Reinhausen /04 EN TRAFOGUARD 71

72 8 Functions and settings θ Hotspot θ Topoil H g r K y t τ Hotspot temperature at time t Current topoil temperature Hotspot factor Gradient of average winding temperature to average oil temperature at rated current Load factor (effective current/rated current) Winding exponent Time Time constant of transformer oil If the temperatures exceed the threshold values set, the respective cooling stages are activated. For the cooling system control to function correctly, you have to set the following parameters. Alternating operation of cooling stages The monitoring system allows equivalent cooling stages to be operated in turn. This spreads the load over several cooling stages and therefore extends the service life. Oil pumps are never operated in turn. Automatic cooling stage activation Load-dependent cooling stage activation Signals and measured values You can use the "Automatic cooling stage activation" function to set the cooling stages to be automatically activated after a certain time. They are then activated regardless of the temperatures measured. You can use the "Load-dependent cooling stage activation" function to set the cooling stages to be activated using the transformer's load current. They are then activated regardless of the temperatures measured. The signals described below are available to you in the cooling system control function package and can be set using the TRAFOSET configuration software: Function Description Limit values Oil temperature, top Hotspot calculated Inlet temperature Monitoring of lower oil temperature of the transformer Monitoring of winding temperature Monitoring of cooler's inlet temperature Signal type 4 Analog: 4 20 ma, PWM or Pt100 Signal source 4 Calculated value 4 Analog: 4 20 ma, PWM or Pt100 Temperature sensor Temperature sensor 72 TRAFOGUARD /04 EN Maschinenfabrik Reinhausen 2014

Failsafe mode is activated if the following errors arise: Failure of a temperature sensor Parameter error TRAFOGUARD has a test function you can use to activate individual cooling stages. You can use a further test function to simulate various temperature values Voltage regulation You can use the "Voltage regulation" function package to automatically regulate the voltage of your transformer. To do this, the voltage regulator compares the transformer's measured output voltage (V actual ) with a defined reference voltage (V desired ). The difference between V actual and V desired is the control deviation (dv). Maschinenfabrik Reinhausen /04 EN TRAFOGUARD 73

74 8 Functions and settings If the control deviation is greater than the specified bandwidth (B%), the voltage regulator emits a switching pulse after a defined delay time T1. The switching pulse triggers an on-load tap-changer tap change which corrects the transformer's output voltage. The voltage regulator parameters can be optimally adjusted to the line voltage behavior to achieve a balanced control response with a small number of tap-change operations. The voltage regulation function package contains the following sub-functions: NORMset NORMset mode enables you to quickly start up voltage regulation. You must set the following parameters for this: Desired value 1 Primary voltage Secondary voltage All other control parameters are determined automatically by the device. Voltage regulation Limit values Line drop compensation Full voltage regulation in which you can define all control parameters yourself. The device has a limit value monitoring function. If a limit value is exceeded, automatic voltage regulation is blocked. If necessary, you can use the line drop compensation function to compensate for the load-dependent voltage drop between the transformer and consumer. The device supports the following methods for this: Line drop compensation Z compensation Motor Current Index With the "Motor Current Index" function package, TRAFOGUARD determines and monitors the Motor Current Index in accordance with IEEE PC TRAFOGUARD /04 EN Maschinenfabrik Reinhausen 2014

The number of free inputs depends on the number of input signals selected. If your selection means that there are inputs available on the cards required, you can use these for any purpose. You can assign a unique signal designation to each free input. You must also define how the ma signal is to be interpreted by the TRAFOGUARD. To do this you need to state the factor, unit and decimal places. Example: If you measure a voltage of between 5.0 and 30.0kV and want to transfer this to the TRAFOGUARD as a ma signal, you need to select k (for kilo) in the factor column and V (for volt) in the unit column. You need to select 1 in the decimal places column. 76 TRAFOGUARD /04 EN Maschinenfabrik Reinhausen 2014

78 8 Functions and settings Parameterizing analog signals Once you have selected the analog signals required, you can parameterize them. You can undertake the following settings: Defining limit values and switch-off hysteresis You need to set the values for 4 ma and 20 ma for ma type signals Defining limit values and switch-off hysteresis Depending on the measured value, you can define up to 2 upper limit values and 2 lower limit values. You can then define what action the monitoring system is to trigger when a limit value is exceeded. You can also define a switch-off hysteresis. If the value falls below the limit value again, including the switch-off hysteresis, the triggered action is deactivated. The switch-off hysteresis prevents actions from being activated and deactivated when the measured value fluctuates around the limit value. The example below shows changes in the measured value and what actions are triggered by the monitoring system when a limit value is exceeded. Figure 54: Limit value monitoring 1 Upper limit value 2 6 Signal/event for "Upper limit value 2 exceeded" 2 Upper limit value 1 7 Signal/event for "Value fallen below lower limit value 1" 3 Lower limit value 1 8 Signal/event for "Value fallen below lower limit value 2" 4 Lower limit value 2 9 Measured value 5 Signal/event for "Upper limit value 1 exceeded" 10 Hysteresis To define the limit values and switch-off hysteresis, proceed as follows: 1.

102 8 Functions and settings Voltage regulation The section below describes how to configure the "Voltage regulation" function package. Use the TAPCON -trol software for this purpose NORMset NORMset mode is used for quickly starting voltage regulation. In NORMset mode, the bandwidth and delay time parameters are automatically adapted to the requirements of the grid. To start NORMset mode, you must set the following parameters: Normset activation Desired value 1 Primary voltage Secondary voltage Line drop compensation cannot be performed in NORMset mode. Set the following parameters to operate the device in NORMset mode. Path: [Parameter set] > Normset > Normset parameter. Normset activation You can use this parameter to activate NORMset mode. A manual tap-change operation is required to activate NORMset. This is how the voltage regulator determines the bandwidth required. If the transformer is switched off, another manual tap-change operation is required. Primary voltage With this parameter, you can set the voltage transformer's primary voltage. Secondary voltage With this parameter, you can set the voltage transformer's secondary voltage. Desired value 1 With this parameter, you can set the desired value for automatic voltage regulation. You can enter the desired value in V or in kv. If you enter the desired value in V, the value relates to the voltage transformer's secondary voltage. If you set the desired value in kv, the value relates to the voltage transformer's primary voltage. 102 TRAFOGUARD /04 EN Maschinenfabrik Reinhausen 2014

103 8 Functions and settings Settings in kv are only possible if you have previously entered the parameters for primary and secondary voltage Control parameters This submenu contains all the parameters required for the control function. Desired value 1, 2 and 3 Bandwidth Delay time T1 Control response T1 Delay time T2 Path: [Parameter set] > Control parameters > Control parameters. Desired value 1, 2, 3 With these parameters, you can set the desired value for automatic voltage regulation. You can enter the desired value in V or in kv. If you enter the desired value in V, the value relates to the voltage transformer's secondary voltage. If you set the desired value in kv, the value relates to the voltage transformer's primary voltage. Settings in kv are only possible if you have previously entered the parameters for primary and secondary voltage. You can specify 3 desired values. Desired value 1 is the default desired value. You can activate desired value 2 or 3 by creating a continuous signal at the IO-X1:17 or IO-X1:16 binary inputs. If there is a signal at both inputs, desired value 2 is active. Bandwidth You can use this parameter to set the maximum permissible deviation in measured voltage V actual. The deviation relates to the activated desired value. Function behavior If the measured voltage V actual is inside the set bandwidth, then no control commands are issued to the on-load tap-changer. Control commands will also not be issued to the on-load tap-changer if the measured voltage returns to the tolerance bandwidth within the set delay time T1. However, if the measured voltage deviates from the set bandwidth for a long period, a tap-change command occurs after the set delay time T1. The on-load tap-changer carries out a tap-change in a positive or negative direction to return to the tolerance bandwidth. Maschinenfabrik Reinhausen /04 EN TRAFOGUARD 103

104 8 Functions and settings Figure 71: Voltage over time 1 + B %: Upper limit 4 Set delay time T1 2 V desired : Desired value 5 V actual : Measured voltage 3 - B %: Lower limit 6 B%: Tolerance bandwidth A C V actual is outside the bandwidth. Delay time T1 starts. V actual is outside the bandwidth. Delay time T1 starts. B D V actual is within the bandwidth before delay time T1 is complete. V actual is still outside the bandwidth when delay time T1 is complete. Tap-change operation is initiated. Determining bandwidth In order to set the correct value, the transformer's step voltage and nominal voltage must be known. You have to set the bandwidth in such a way that the output voltage of the transformer (V actual ) returns to within the specified tolerance bandwidth after the tap change. If too small a bandwidth is defined, the output voltage exceeds the bandwidth selected and the device must immediately issue a tapchange command in the opposite direction. If a very large bandwidth is selected, this results in a major control deviation. The following value is recommended for the bandwidth setting: V n-1 Step voltage of tap position n-1 V n V nom Step voltage of tap position n Nominal voltage 104 TRAFOGUARD /04 EN Maschinenfabrik Reinhausen 2014

105 8 Functions and settings The following transformer parameters are used for determining the recommended bandwidth: Nominal voltage V nom = V Step voltage in tap position 4 V Step4 = V Step voltage in tap position 5 V Step5 = V Delay time T1 Delay time T1 delays the issuing of a tap-change command for a defined period. This function prevents unnecessary tap-change operations if the tolerance bandwidth is exited. If the current measured voltage exits the bandwidth, delay time T1 starts. This is shown in the display by the time bar filling and the remaining time being indicated. If the control deviation is still present after the delay time, a tap-change command is issued. If during the delay time the measured voltage returns to within the tolerance bandwidth, the delay time still running is counted down in seconds starting from the time already expired. The absolute time display disappears from the display. The time bar is shown hatched and shrinks steadily. If the measured voltage again exceeds the set bandwidth, then the time delay is restarted from the remaining time. Control response T1 The control response T1 can be set to linear or integral. Linear control response T1 Integral control response T1 With linear control response, the device responds with a constant delay time regardless of the control deviation. With integral control response, the device responds with a variable delay time depending on the control deviation. The greater the control deviation (ΔV) in relation to the set bandwidth (B), the shorter the delay time. The delay time can therefore be reduced down to 1 second. This means that the device responds faster to large voltage changes in the grid. Regulation accuracy improves as a result but the frequency of tap-changes increases too. Maschinenfabrik Reinhausen /04 EN TRAFOGUARD 105

106 8 Functions and settings Figure 72: Diagram showing integral control response ΔV/B Control deviation "ΔV" as % of desired value as ratio to the set bandwidth "B" as % of desired value 1 "Delay time T1" parameter Delay time T2 With this parameter, you can set delay time T2. Delay time T2 is used to compensate for large control deviations faster. The delay time T2 only takes effect if more than one tap-change operation is required for returning the voltage to within the set bandwidth. The first output pulse occurs after the set delay time T1. After the set delay time T2 has elapsed, additional pulses occur in order to correct the existing control deviation. The delay time T2 must be greater than the pulse duration and the maximum operating time of the motor-drive unit. T2 activation With this parameter, you can activate the delay time T2 function Limit values This sub-menu contains the parameters for monitoring the limit values. [Parameter set] > Control parameters > Limit values. 106 TRAFOGUARD /04 EN Maschinenfabrik Reinhausen 2014

107 8 Functions and settings Function monitoring If the bandwidth is exceeded for more than 15 minutes, the device issues the Function monitoring event message and the associated relay is activated. You can use this parameter to activate or deactivate the function monitoring. V< blocking You can use this parameter to set how the device behaves if the voltage falls below the undervoltage limit. You can select the following options: Setting On Off Table 26: Behavior Function Automatic regulation is blocked. Automatic regulation remains active. V< Delay You can use this parameter to set the delay time after which the Undervoltage relay is to activate. This can be used to prevent messages from being issued when the value briefly falls below the limit value. The undervoltage LED always lights up immediately regardless. V< also under 30 V With this parameter, you can set whether the undervoltage message is to be suppressed at a measured value of less than 30 V. This setting is used to ensure that no event message appears when the transformer is switched off. You can select the following options: Setting On Off Table 27: Behavior Function The Undervoltage message is also displayed when the measured value is less than 30 V. The Undervoltage message is no longer displayed when the measured value is less than 30 V Compensation You can use the "Compensation" function to compensate for the load-dependent voltage drop between the transformer and consumer. The device provides 2 methods of compensation for this purpose: R&X compensation (line drop compensation) Z compensation Maschinenfabrik Reinhausen /04 EN TRAFOGUARD 107

108 8 Functions and settings You can use R&X compensation and Z compensation at the same time. If you do not want to use one method, you have to set the associated parameters to 0. If you are using the IEC control system protocol, you can only activate one of the two compensation methods at any one time. A control system command is available for this. Also refer to 2 Setting transformer circuit [ 57] R&X compensation R&X compensation (LDC) requires exact cable data. Line voltage drops can be compensated very accurately using LDC. To set R&X compensation correctly, you need to calculate the ohmic and inductive voltage drop in V with reference to the secondary side of the voltage transformer. You also need to correctly set the transformer circuit [ 57] used. Figure 73: Equivalent circuit Figure 74: Phasor diagram You can calculate the ohmic and inductive voltage drop using the following formulas. This voltage drop calculation relates to the relativized voltage on the secondary side of the voltage transformer. 108 TRAFOGUARD /04 EN Maschinenfabrik Reinhausen 2014

Path: [Parameter set] > Control parameters > Compensation Ohmic voltage drop Ur You can use this parameter to set the ohmic voltage drop (ohmic resistance load). If you do not want to use line drop compensation, you have to set the value 0.0 V. Inductive voltage drop Ux You can use this parameter to set the inductive voltage drop (inductive resistance load). The compensation effect can be rotated by 180 in the display using a plus or minus sign. If you do not want to use line drop compensation, you have to set the value 0.0 V. Also refer to 2 Setting transformer circuit [ 57] Maschinenfabrik Reinhausen /04 EN TRAFOGUARD 109

110 8 Functions and settings Z compensation To keep the voltage constant for the consumer, you can use Z compensation to activate a current-dependent increase in voltage. You can also define a limit value to avoid excess voltage on the transformer. Figure 75: Z compensation To use Z compensation, you need to calculate the increase in voltage (ΔU) taking the current into account. Use the following formula for this purpose: U Voltage increase I Load current in A U Tr U Load Transformer voltage with current I Voltage on line end with current I and on-load tapchanger in same operating position I N k CT Nominal current of currenttransformer connection in A ( ) Current transformer ratio Sample calculation: U Tr = V, U Load = V, I N = 5 A k CT = 200 A/5 A, I = 100 A Produces a voltage increase U of 0.2% The following sections describe how you can set the parameters you need for Z compensation. You can set the parameters for line drop compensation in the Compensation sub-menu. Path: [Parameter set] > Control parameters > Compensation Z compensation This parameter sets the voltage increase V previously calculated. 110 TRAFOGUARD /04 EN Maschinenfabrik Reinhausen 2014

111 8 Functions and settings If you do not want to use Z compensation, you have to set the value 0.0 %. Z compensation limit value You can use this parameter to define the maximum permissible voltage increase to avoid excess voltage on the transformer. If you do not want to use a limit value, you have to set the value 0.0 % General Path: [Parameter set] > Configuration > General Raise/Lower pulse duration You can use this parameter to set the duration of the switching pulse for the motor-drive unit. If you set the switching pulse time to 0 s, the motor-drive unit is activated with a continuous signal. The signal then remains active for as long as the or keys are pressed. Switching pulse in normal mode If you set the switching pulse time to 1.5 seconds for example, after the set delay time T1 or delay time T2 there will be a switching pulse of 1.5 seconds. The waiting time between 2 consecutive switching pulses corresponds to the set delay time T1 or delay time T2. Maschinenfabrik Reinhausen /04 EN TRAFOGUARD 111

112 8 Functions and settings Figure 76: Switching pulse time in normal mode 1 Set delay time T1 or T2 2 Set switching pulse time (for example 1.5 seconds) If the motor-drive unit does not start with the factory setting (1.5 seconds), you need to extend the raise switching pulse time / lower switching pulse time. Switching pulse for rapid return control If you set the raise switching pulse time or lower switching pulse time to 1.5 seconds, for example, the next earliest switching pulse occurs in rapid return control mode 1.5 seconds after the previous switching pulse ended. 112 TRAFOGUARD /04 EN Maschinenfabrik Reinhausen 2014

The motor-drive unit's runtime can also be monitored by the device. This function is used to identify motor-drive unit malfunctions during the tap-change operation and to trigger any actions needed. Behavior Parameterizing control input The motor-drive unit issues the Motor-drive unit running signal during the tap-change operation. This signal is present until the tap-change operation is complete. The device compares the duration of this signal with the set motor runtime. If the set motor runtime is exceeded, the device triggers the following actions: 1. Motor runtime monitoring message is issued 2. Continuous signal via output relay Motor-drive unit runtime exceeded (optional) 3. Pulse signal via Trigger motor protective switch output relay (optional) To use runtime monitoring, you need to correctly wire the corresponding control input and parameterize to Motor running. The motor runtime must also be set. Maschinenfabrik Reinhausen /04 EN TRAFOGUARD 113

114 8 Functions and settings Parallel operation In theparallel operation menu item, you can set the parameters needed for parallel transformer operation. Parallel transformer operation is used to increase the throughput capacity or short-circuit capacity in one place. Conditions for parallel operation Compliance with the following general conditions is required for operating transformers in parallel: Identical rated voltages Transformer power ratio (< 3 : 1) Maximum deviation of short-circuit voltages (U K ) for transformers connected in parallel < 10% Same number of switching groups The same current-transformer connection has to be used for all devices running in parallel You can control up to 16 transformers connected in parallel in one or 2 groups without detecting the system topology. Information is swapped between the voltage regulators operating in parallel using the CAN bus. Parallel operation is activated using one of 2 status inputs or the control system. Parallel operation method The device supports parallel operation following the methods described below: Parallel operation following the "Circulating reactive current minimization" principle Parallel operation following the "Tap synchronization" (master/follower) principle You must select the same parallel operation method (circulating reactive current minimization or tap synchronization) for all voltage regulators operating in parallel. Otherwise you cannot operate the devices in parallel. The following sections describe how you can set the parameters. Ensure that you have set the following parameters when activating parallel operation: CAN bus address Assigning CAN bus address You can use this parameter to assign a CAN bus address to the device. So that all devices can communicate using the CAN bus, each device requires a unique identifier. Addresses can be set from 1 to 16. If the value is set to 0, then no communication takes place. Path: [Parameter set] > Configuration > Parallel operation 114 TRAFOGUARD /04 EN Maschinenfabrik Reinhausen 2014

115 8 Functions and settings Selecting parallel operation method You can use this parameter to select a parallel operation method. Two different methods can be assigned to the device. Circulating reactive current minimization Tap synchronization (master/follower) You must select the same parallel operation method for all voltage regulators operating in parallel. The following sections describe how you can set the parameters for a parallel operation method Setting circulating reactive current method When the circulating reactive current parallel operation method is selected, then parallel operation is carried out using the circulating reactive current minimization method. The circulating reactive current is calculated from the transformer currents and their phase angles. A voltage proportional to the circulating reactive current is added to the independently operating voltage regulators as a correction for the measurement voltage. This voltage correction can be reduced or increased using the circulating reactive current sensitivity setting. The circulating reactive current method is suited to transformers connected in parallel with a similar nominal output and short-circuit voltage V K and to vector groups with the same and different step voltages. This does not require any information about the tap position. Path: [Parameter set] > Configuration > Parallel operation When using the circulating reactive current parallel operation method, you have to set the parameters for the circulating reactive current sensitivity and circulating reactive current blocking. Setting circulating reactive current sensitivity The circulating reactive current sensitivity is a measure of its effect on the behavior of the voltage regulator. At a setting of 0 % no effect is present. With circulating reactive current relating to the rated current of the current transformer, if you set the value to 10 % for example, this would cause the voltage in the voltage regulator to be corrected by 10 %. This correction to the voltage can be increased or decreased with this setting to attain the optimum value. As soon as you change the circulating reactive current sensitivity value, the value for the result changes in the help text in the display. Path: [Parameter set] > Configuration > Parallel operation Maschinenfabrik Reinhausen /04 EN TRAFOGUARD 115

116 8 Functions and settings Setting circulating reactive current blocking You can use this parameter to set the limit value for the maximum permissible circulating reactive current. If, during parallel operation, the circulating reactive current exceeds the set limit value, then the following event is activated: Problem with parallel operation All devices operating in parallel are blocked. Depending on the set delay time for the parallel operation error message, the signaling relay Problem with parallel operation is activated. Path: [Parameter set] > Configuration > Parallel operation Setting tap synchronization With the tap synchronization method, you need to designate one voltage regulator as the master and all others as followers. The master handles voltage regulation and transmits its latest tap positions to all followers via the CAN bus. The followers compare the tap position received with their own tap position. If the set permissible tap difference between the tap position received and their own position is exceeded, the followers switch to the tap position received from the master. This ensures that the transformers operating in parallel are always in the same tap position. For the tap synchronization method, you can select the following options: Option Master Follower Sync.auto Description Table 28: Tap synchronization method The voltage regulator is designated as the master. The voltage regulator is designated as the follower. Automatic assignment of master or follower. If no master is detected, the voltage regulator with the lowest CAN bus address is automatically designated as the master. All other voltage regulators are designated as followers. In parallel operation, an individual CAN bus address must be assigned to each voltage regulator. Up to 16 CAN participants are supported. If you select Off, parallel operation is deactivated. Path: [Parameter set] > Configuration > Parallel operation Selecting the follower tapping direction You can use this parameter to correct the follower's switching direction, without re-configuring the system. Since in parallel operation using the Tap synchronization master/follower method the tap positions of the transformers which are running in parallel are compared, it is absolutely essential that 116 TRAFOGUARD /04 EN Maschinenfabrik Reinhausen 2014

117 8 Functions and settings these transformers have the same tap position designation and that the "Raise" or "Lower" signals produce the same voltage change in all transformers. Swapped switching direction If you have wired the device such that a RAISE operation results in lower voltage, you can use this parameter to swap the switching direction. If the switching direction is swapped, the "Lower" relay is activated during a voltage RAISE operation. The wiring no longer has to be corrected. But be sure that the wiring between the device and motor-drive unit is correct. Parameters Standard Swapped Table 29: Device behavior Definition A raise signal results in the follower switching up one step to increase the voltage. A lower signal results in the follower switching down one step to decrease the voltage. A raise signal results in the follower switching down one step to increase the voltage. A lower signal results in the follower switching up one step to decrease the voltage. Ensure that you only set this parameter for the follower. The tapping direction can only be swapped for a follower. Path: [Parameter set] > Configuration > Parallel operation Setting delay time for parallel operation error messages You can use this parameter to set the delay time for a parallel operation error message so that brief fault messages are not received if the motor-drive units involved in the parallel operation have different runtimes. Once the set delay time has elapsed, the event is issued at the output relay. Automatic regulation is blocked and the on-load tap-changers can only be adjusted in manual mode. Path: [Parameter set] > Configuration > Parallel operation Deactivating parallel operation To deactivate parallel operation, you have to set the option Off for the parallel operation method parameter. Path: [Parameter set] > Configuration > Parallel operation Password protection The device can be protected against unauthorized use by a password.
