Operation principle
Two step overvoltage protection OV2PTOV (59) is used to detect high power system
voltage. OV2PTOV (59) has two steps with separate time delays. If one-, two- or
three-phase voltages increase above the set value, a corresponding PICKUP signal is
issued. OV2PTOV (59) can be set to PICKUP/TRIP, based on 1 out of 3, 2 out of 3 or 3
out of 3 of the measured voltages, being above the set point. If the voltage remains
above the set value for a time period corresponding to the chosen time delay, the
corresponding trip signal is issued.
The time delay characteristic is individually chosen for the two steps, and can be either
definite time or inverse time delayed.
The voltage related settings are made in percent of the global set base voltage VBase,
which is set in kV, phase-to-phase.
OV2PTOV (59) can be set to measure phase-to-ground fundamental value, phase-to-
phase fundamental value, phase-to-ground RMS value or phase-to-phase RMS value.
The choice of measuring is done by the parameter ConnType.
The setting of the analog inputs are given as primary phase-to-ground or phase-to-
phase voltage. OV2PTOV (59) will trip if the voltage gets higher than the set
percentage of the set base voltage VBase. This means operation for phase-to-ground
voltage over:
