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].P
ICKUP
A« or »27M[1].T
RIP
A« => pickup or trip caused by phase voltage
»VA«.
»27M[1].P
ICKUP
B« or »27M[1].T
RIP
B« => pickup or trip caused by phase voltage
»VB«.
»27M[1].P
ICKUP
C« or »27M[1].T
RIP
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].P
ICKUP
A« or »27M[1].T
RIP
A« => pickup or trip caused by phase-to-phase
voltage
»VAB«.
»27M[1]. P
ICKUP
B« or »27M[1].T
RIP
B« => pickup or trip caused by phase-to-phase
voltage
»VBC«.
»27M[1]. P
ICKUP
C« or »27M[1].T
RIP
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.
