Control unit

The motor-drive unit is equipped with a control unit which enables automatic
voltage regulation. This is used to keep the output voltage of a transformer
with an on-load tap-changer constant. The control unit compares the trans-
former's measured voltage (U

actual

) with a defined reference voltage (U

desired

).

The difference between U

actual

and U

desired

is the control deviation dU. If the

control deviation dU is greater than the set bandwidth, the control unit trig-
gers a tap-change operation after the delay time T1 has elapsed in order to
reduce the control deviation.

You can set all parameters needed to set the voltage regulation via a param-
eterization menu.

OLTC PreCheck

Before each tap-change operation, the motor-drive unit checks whether the
drive train of the on-load tap-changer is tight or whether one or more micro-
switches have failed. In the event of a micro-switch defect, the device
switches to fault mode and issues an error message.

Exception: In the EXTERNAL CONTROL operating mode, the device per-
forms an automatic OLTC-PreCheck once every 24 hours, not before each
tap-change operation.

Behavior in the event of a voltage interruption

Should a voltage interruption occur during a tap-change operation, the mo-
tor-drive unit completes the tap-change operation that has already started.
Open both relay contacts on X5 and the device will block further on-load tap-
change operations until the voltage supply is restored. You can adapt this re-
sponse using the "Target position for loss of voltage" [

Section 7.4.4, Page

81] function so that the on-load tap-changer is changed to a defined tap po-
sition before this blocking. For this purpose, the control unit is equipped with

an energy accumulator. If it is ready to work, this is indicated by the

LED

staying lit. After a loss of voltage or a deliberate disconnection from the
mains, it takes around 30 minutes for this energy accumulator to discharge.

3.3 Operating modes

The control ensures that the required cooling time of approx. 3 seconds is
maintained after each on-load tap-change operation. During this time, the
control will not accept any tap-change commands. An exception to this is
the optional multi-tap-change function, which is only possible in the operat-
ing mode EXTERNAL CONTROL.

There are 3 operating modes on the control unit for controlling the on-load
tap-changer.
