ABB REG670 - Voltage Protection; Overexcitation Protection OEXPVPH; Two Step Overvoltage Protection OV2 PTOV; Two Step Residual Overvoltage Protection ROV2 PTOV

11.6.4 Voltage protection
The viewable data available under voltage protection are mainly trip related and
comprise data regarding undervoltage, overvoltage, residual overvoltage and
overexcitation.
11.6.4.1
Overexcitation protection OEXPVPH
Main menu/Test/Function status/Voltage protection/Overexcitation(PVPH,24)/
OEX
Displays available instances of OEXPVPH with a number of measurements per
instance. These measurements indicate whether values are out of the measuring
range (ERROR) and if the overexcitation function has caused a trip (TRIP). The
thermal status as a percentage of the trip level and the calculated time to trip are
among the other outputs available here.
11.6.4.2 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.
11.6.4.3 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.
11.6.4.4 100% Stator earth fault protection, 3rd harmonic based STEFPHIZ
Main menu/Test/Function status/Voltage protection/StatorEF3Harm(PHIZ,
59THD)/TRV
Shows available instances of STEFPHIZ .
11.6.4.5 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.
