5.4.8.2 PHASE OVERVOLTAGE UNIT (59P)
59P unit is a phase overvoltage protection element that uses as input magnitudes the phase-to-phase voltages, either
measured directly from the voltage inputs in case the type of connection (General Setpoint > Phase VT Connection) is
DELTA, or calculated from the phase-to-ground voltages in the case of a wye connection. The time delay can be set from
instantaneous to 900 seconds. The unit reset can be delayed up to 900 seconds.
As in the case of the undervoltage unit, this unit generates independent pickup and trip signals for each phase. The general
signal is selectable by setpoint to be an OR or an AND of the phase signals.
Table 5–60: 59P UNIT SETPOINTS
Phase overvoltage unit setpoints are:
Function Permission (Function): This setpoint indicates whether the phase overvoltage element is enabled or disabled.
Pickup Level: This is the voltage threshold over which the overvoltage unit will operate.
Trip time (Trip Delay): setpoint of the Protection element operation time.
Reset time (Reset Delay): Reset time of the Protection element.
Operation logic (Logic): This setpoint allows the unit operation logic selection:
ANY PHASE The unit will operate under an overvoltage condition in any of the
three phases.
TWO PHASES The unit will operate under an overvoltage condition in at least two
phases.
ALL PHASES The unit will operate under an overvoltage condition in the three
phases.
Snapshot Events: The snapshot event setpoint enables or disables the snapshot event generation for
this unit.
