The ground instantaneous overcurrent element can be used as an instantaneous element with no intentional delay or as a
definite time element. The ground current input is the quantity measured by the ground input CT and is the fundamental
phasor magnitude.

NEGATIVE SEQUENCE CURRENT
The L60 provides two negative-sequence time overcurrent elements, two negative-sequence instantaneous overcurrent
elements, and two negative-sequence directional overcurrent elements. For information on the negative sequence time
overcurrent curves, see the Inverse TOC Curve Characteristics section earlier.

These elements measure the current that is connected to the ground channel of a CT/VT module. The conversion
range of a standard channel is from 0.02 to 46 times the CT rating.
