This element is intended for monitoring overvoltage conditions of the auxiliary voltage. A typical application for this element
5
is monitoring the zero-sequence voltage (3V_0) supplied from an open-corner-delta VT connection. The nominal secondary
voltage of the auxiliary voltage channel entered under
is the p.u. base used when setting the pickup level.
