5.6 GROUPED ELEMENTS
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.
NOTE
This channel may be also equipped with a sensitive input. The conversion range of a sensitive channel is from
0.002 to 4.6 times the CT rating.

The ground instantaneous overcurrent element may 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.
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.
NOTE
This channel may be equipped with a standard or sensitive input. The conversion range of a sensitive channel is
from 0.002 to 4.6 times the CT rating.
