Power swing detection ZMRPSB (78)

Main menu/Test/Function status/Impedance protection/
PowerSwingDetection(RPSB,78)/PSD1
Displays one instance of ZMRPSB (78) with three measurements. These indicate a
power swing and show the measured impedances for the inner and outer impedance
boundaries.

Power swing logic ZMRPSL

Main menu/Test/Function status/Impedance protection/PowerSwingLogic(RPSL)/
PSL
Displays the output data of ZMRPSL.

Current protection

Viewable data under Current protection consists mainly of trip status data under the
various categories of current protection which include overcurrent protection, thermal
overload, stub protection, pole discrepancy and variations of these.

Breaker failure protection CCRBRF (50BF)

Main menu/Test/Function status/Current protection/BreakerFailure(RBRF,
50BF)/BFP
Displays an application dependent number of instances of CCRBRF (50BF) with some
measurements per instance. The measurement outputs include trip status and faulty
circuit breaker alarm.

Broken conductor check BRCPTOC (46)

Main menu/Test/Function status/Current protection/BrokenConductor(PTOC,
46)/BRC
Displays the output data of BRCPTOC (46).

Directional over-power protection GOPPDOP (32)

Main menu/Test/Function status/Current protection/DirOverPowerProt(PDOP,
32)/GOP
Displays the output data of GOPPDOP (32).
