Supervision
Loss of Potential - Fuse Failure
VT Supervision via digital inputs (Fuse Failure)
The module
»LOP« is capable of detecting a fuse failure at the secondary side of the VTs as long as the automatic
circuit breakers of the VTs are connected with the device via a digital input and if this input is assigned to the
module
»LOP«.
Setting the Parameters for detecting a fuse failure (FF) of a phase voltage transformer
In order to detect a fuse failure of a phase voltage transformer via digital input, please proceed as follows:
Assign a digital input onto the parameter »
LOP.Ex FF VT« that represents the state of the automatic circuit
breaker of the phase voltage transformer.
Set the parameter »
Measuring Crcuit Supervison=active« within all those protective elements, that should be
blocked by a fuse failure
.
Setting the Parameters for detecting a fuse failure (FF) of a earth phase voltage transformer
In order to detect a fuse failure of a phase voltage transformer via digital input, please proceed as follows:
Assign a digital input onto the parameter »
LOP.Ex FF EVT« that represents the state of the automatic circuit
breaker of the phase voltage transformer.
Set the parameter »
Measuring Crcuit Supervison=active« within all those protective elements, that should be
blocked by a fuse failure
