M13808-3 v11
Residual voltages may occur in the power system during earth faults.
Two step residual overvoltage protection (ROV2PTOV) function calculates the
residual voltage from the three-phase voltage input transformers or measures it
from a single voltage input transformer fed from an open delta or neutral point
voltage transformer.
ROV2PTOV has two voltage steps, each with inverse or definite time delay.
A reset delay ensures operation for intermittent earth faults.
