14.4.2 Functionality
Tap changer control and supervision, 6 binary inputs TCMYLTC as well as Tap
changer control and supervision, 32 binary inputs TCLYLTC are is used for control
of power transformers with a on-load tap changer. The functions provide automatic
regulation of the voltage on the secondary side of transformers or alternatively on a
load point further out in the network.
Control of a single transformer, as well as control of up to eight transformers in
parallel is possible. For parallel control of power transformers, three alternative
