There are three phase overvoltage elements available. A phase overvoltage element is 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 figure
shows specific voltages to be used for each phase.
