Voltage protection

The viewable data available under voltage protection are mainly trip related and
comprise data regarding undervoltage, overvoltage, residual overvoltage and
overexcitation.

Loss of voltage check LOVPTUV

Main menu/Test/Function status/Voltage protection/LossofVoltage(PTUV,27)/
LOV
Displays the output data of LOVPTUV.

Two step overvoltage protection OV2PTOV

Main menu/Test/Function status/Voltage protection/OverVoltage2Step(PTOV,
59)/TOV
Displays available instances of OV2PTOV with several measurements per
instance. The measurements include operate/trip and start signal data.

Two step residual overvoltage protection ROV2PTOV

Main menu/Test/Function status/Voltage protection/
ResidualOverVoltage2Step(PTOV,59N)/TRV
Displays available instances of ROV2PTOV with some measurements per instance.
The measurements include operate/trip and signal data.

Two step undervoltage protection UV2PTUV

Main menu/Test/Function status/Voltage protection/
UnderVoltage2Step(PTUV, 27)/TUV
Displays available instances of UV2PTUV with several measurements per
instance. The measurement data includes operate/trip signals and start signals.

Voltage differential protection VDCPTOV

Main menu/Test/Function status/Voltage protection/VoltageDiff(PTOV,60)/
VDC
Displays the output data of VDCPTOV.

Frequency protection

The measurements generated by the Underfrequency, Overfrequency and Rate-of-
change of frequency functions are available under the paths outlined below.
