5.5.2 Voltage transformer supervision (60)
Voltage transformer supervision is used to detect errors in the secondary circuit of the voltage
transformer during fuse failure. This signal is mostly used as an alarming function or to disable
functions that require adequate voltage measurement.

The following figure presents a simplified function block diagram of the voltage transformer
supervision function.
