Protective Elements
If phase voltages are applied to the measuring inputs of the device and field
parameter
»VT con«
is set to
»Phase-to-neutral«
, the messages issued by the
voltage protection module in case of actuation or trip should be interpreted as
follows:
»V[1].ALARM L1« or »V[1].TRIP L1« => alarm or trip caused by phase voltage
»VL1«
.
»V[1].ALARM L2« or »V[1].TRIP L2« => alarm or trip caused by phase voltage
»VL2«
.
»V[1].ALARM L3« or »V[1].TRIP L3« => alarm or trip caused by phase voltage
»VL3«
.
If, however, line-to-line voltages are applied to the measuring inputs and field
parameter
»VT con«
is set to
»Phase to Phase«
, then the messages should be
interpreted as follows:
»V[1].ALARM L1« or »V[1].TRIP L1« => alarm or trip caused by line-to-line
voltage
»V12«
.
»V[1].ALARM L2« or »V[1].TRIP L2« => alarm or trip caused by line-to-line
voltage
»V23«
.
»V[1].ALARM L3« or »V[1].TRIP L3« => alarm or trip caused by line-to-line
voltage
»V31«
