ABB RET670 User 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.
