, the messages issued by the voltage protection module
in case of actuation or trip should be interpreted as follows:
»27M[1].PICKUP A« or »27M[1].TRIP A« => pickup or trip caused by phase voltage
»VA«
.
»27M[1].PICKUP B« or »27M[1].TRIP B« => pickup or trip caused by phase voltage
»VB«
.
»27M[1].PICKUP C« or »27M[1].TRIP C« => pickup or trip caused by phase voltage
»VC«
.
However, if line-to-line voltages are applied to the measuring inputs and field parameter

«
is set to
»Phase to Phase«
, then the messages should be interpreted as
follows:
»27M[1].PICKUP A« or »27M[1].TRIP A« => pickup or trip caused by phase-to-phase
voltage
»VAB«
.
»27M[1]. PICKUP B« or »27M[1].TRIP B« => pickup or trip caused by phase-to-phase
voltage
»VBC«
.
»27M[1]. PICKUP C« or »27M[1].TRIP C« => pickup or trip caused by phase-to-phase
voltage
»VCA«
Criterion - Measuring Method
For all protection elements it can be determined, whether the measurement is done on basis of the »
Fundamental«
or if
»
True RMS«
measurement is used.
Dropout Ratio
The dropout ratio is settable.
