3.1 On-load tap-changer

3.1.1 Function description

On-load tap-changers are used to adjust the transmission ratio of transform-
ers without interrupting the load flow. This makes it possible to compensate
for aspects such as fluctuations in voltage occurring in the power transmis-
sion grid. For this purpose, on-load tap-changers are fitted in transformers
and connected to the active part of the transformer.

A motor-drive unit which receives a control impulse (e.g. from a voltage reg-
ulator) changes the operating position of the on-load tap-changer, as a result
of which the transformer's transmission ratio is adapted to the prevailing op-
erating requirements.
