PHASE OVERVOLTAGE1
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 cal-
culated from phase-to-ground (wye) connected VTs. The specific voltages to be used for each phase are shown below.
