This element can provide a desired time-delay operating characteristic versus the applied current or be used as a simple
definite time element. The ground current input value is the quantity measured by the ground input CT and is the funda-
mental phasor or RMS magnitude. Two methods of resetting operation are available: "Timed" and "Instantaneous" (see the
