 PHASE
 OVERVOLTAGE1
There are three phase overvoltage elements available. A phase overvoltage element is used as an instantaneous element
5
with no intentional time delay or as a definite time element. The input voltage is the phase-to-phase voltage, either mea-
sured directly from delta-connected VTs or as calculated from phase-to-ground (wye) connected VTs. The specific voltages
to be used for each phase are shown below.
If the source VT is wye-connected, then the phase overvoltage pickup condition is
and V .
