Function description
The motor-drive unit adjusts the operating position of on-load tap-changers
in regulating transformers to the individual operating requirements.
The tap-change operation is activated by starting the motor-drive unit (a sin-
gle control impulse triggered, for example, by a voltage regulator of the
TAPCON®-series). This operation is always completed regardless of any
other control pulses emitted during the tap-change operation. In the standard
design, the next tap-change operation can only proceed once all control de-
vices have reached their resting positions.
Behavior in the event of a voltage interruption
Should the voltage be interrupted during an on-load tap-change operation,
once the voltage supply returns, the motor-drive unit completes the started
on-load tap-change operation.
