WebGround distance functions measure an apparent impedance to the fault based on the ratio of relay voltage to relay current. A variety of ground distance relay characteristics have been used: reactance, mho, and quadrilateral for example. The simplest ground distance functions use only a single phase current and a single phase voltage.
