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.

Figure140: Behavior of the regulation function with delay times T1 and T2

1 Upper limit of bandwidth 4 Set delay times T1 and T2.

2 Desired value 5 Control variable measured value

3 Lower limit of bandwidth 6 Bandwidth range

A Control variable is outside of the

bandwidth. Delay time T1 starts.

B Delay time T1 complete. Tap

change triggered.

C Delay time T2 complete. Tap

change triggered.

Activate delay time T2

You can use this parameter to activate or deactivate the delay time T2.

9.18 Transformer data

The transformation ratios and measuring set-up for the voltage and current

transformers used in the system can be set with the following parameters.

The device uses this information to calculate the corresponding measured

values on the primary side of the current transformer (and therefore the

transformer) from the recorded measured values. These are then displayed.
