Operator's manual
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.

Two step overvoltage protection OV2PTOV

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