5.4.8.2 PHASE OVERVOLTAGE ELEMENT (59P)
The Phase overvoltage element may be used as an instantaneous element with no intentional time delay or as a Definite
Time element. The input voltage is the phase-to-phase voltage, either measured directly from Delta-connected VTs or as
calculated from phase-to-ground (wye) connected VTs. The time delay can be set from instantaneous to 900 seconds. The
element reset can be delayed up to 900 seconds.
As in the case of the undervoltage element, this element generates independent pickup and trip signals for each phase.
The general signal is selectable by setting to be an OR or an AND of the phase signals.
Table 5–62: 59P ELEMENT SETTINGS
Phase overvoltage element settings are:
Function Permission (Function): This setting indicates whether the phase overvoltage element is enabled or disabled.
Pickup Level: This is the voltage threshold over which the overvoltage element will operate.
Trip time (Trip Delay): setting of the Protection element operation time.
Reset time (Reset Delay): Reset time of the Protection element.
Operation logic (Logic): This setting allows the element operation logic selection:
ANY PHASE The element will operate under an overvoltage condition in any of the
three phases.
TWO PHASES The element will operate under an overvoltage condition in at least
two phases.
ALL PHASES The element will operate under an overvoltage condition in the three
phases.
Snapshot Events: The snapshot event setting enables or disables the snapshot event generation for this
element.
