9 Operation starts to count down. Once delay time T2 is complete, a control impulse is again issued to the motor-drive unit for the tap change to return to the tol- erance bandwidth.

9 Operation 9.3.2.1 R&X compensation R&X compensation can compensate for voltage losses on the lines and therefore ensure correct voltage at the load. This requires precise line data. After you have entered all of the line data, the device automatically calcu- lates the ohmic and inductive voltage drop and takes this into account for au- tomatic voltage regulation.

9 Operation Ohmic resistance load You can use this parameter to set the ohmic resistance load. Inductive resistance load You can use this parameter to set the inductive resistance load. Length of line You can use this parameter to set the length of line. 9.3.2.2 Z compensation To keep the voltage constant for the consumer, you can use Z compensation to activate a current-dependent voltage increase.
9 Operation 1. Go to Settings > Parameters > On-load tap-changer regulator > Com- pensation. 2. Select the desired parameter. 3. Set the desired parameter. 4. Press the Accept button to save the modified parameter. Voltage increase You can use this parameter to set the current-dependent voltage increase ∆U.

9 Operation 9.3.3.1.1 Tap synchronization With the tap synchronization parallel operation method, one voltage regu- lator works as the master and all others as followers. Master Follower Tap position CAN bus Figure 56: Tap synchronization The master handles voltage regulation and transmits its current tap positions to all followers via the CAN bus.

Page 124
9 Operation The circulating reactive current method is suited to transformers connected in parallel with a similar nominal output and short-circuit voltage U and to vector groups with the same and different step voltages. This does not re- quire any information about the tap position. Note that the following prerequisites must be met for the "circulating reactive current minimization"...
Page 125
9 Operation current is added to the independently regulating voltage regulators as a cor- rection for the control deviation determined on the basis of the measurement voltage. This extra control deviation depends on how much the measured power factor deviates from the desired power factor. To use the power factor method, you need to know the conditions of your network in order to correctly set the device parameters.

9 Operation Desired power factor You can use this parameter to set the power factor, which the transformer has under normal operating conditions. If the measured power factor devi- ates from the desired one, the device calculates a correction which is added to the control deviation.

9 Operation 9.3.4 U bandwidth monitoring The following limit values are monitored via bandwidth monitoring. The set bandwidth [►Page 114] (upper/lower) of the voltage regulation is used for this purpose. Behavior If the measured value is higher than the upper limit or lower than the lower limit, the device triggers the Upper bandwidth limit value / Lower bandwidth limit value message.

9 Operation 9.4.2 Tap position capture method The current tap position of the on-load tap-changer is transmitted from the motor-drive unit to the device. You can use this parameter to select the type of tap position capture. In order to ensure proper function of the tap position capture, make sure that the inputs of the corresponding tap position capture method are acti- vated and correctly wired.
