Over-voltage
A term used to describe how the relay behaves during a fault
condition. For example, a distance relay is overreaching when
the impedance presented to it is smaller than the apparent
impedance to the fault applied to the balance point, that is, the
set reach. The relay "sees" the fault but perhaps it should not
have seen it.
