Overview
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.
For more detailed information on “Phase overvoltage” element, refer to GE, Universal Relay (UR) family of products, Version 8.0x manuals.
