Voltage-Transformer Supervision of Side 2

Description

General
In practice, voltage-transformer faults occur rather rarely. More frequently, it is the fuses connected in series
to the voltage transformers which fail. Such a failure is detected by the voltage transformer supervision func-
tion and signaled with a warning indication. 1-, 2-, and 3-phase faults are detected.
The limit values and delay times for the function can be parameterized.
