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
5
calculated from phase-to-ground (Wye) connected VTs. The specific voltages to be used for each phase are shown on the
logic diagram.
