If phase voltages are applied to the measuring inputs of the device and field
parameter » Main VT Con « is set to » Wye « , 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 » Main VT Con « 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.
