The ground current input value is the quantity measured by the ground input CT and is the funda-mental phasor magnitude.Figure 5–47: GROUND IOC1 SCHEME LOGICThese elements measure the current that is connected to the ground channel of a CT/VT module. This channelmay be equipped with a standard or sensitive input. The conversion range of a standard channel is from 0.02 to 46times the CT rating. The conversion range of a sensitive channel is from 0.002 to 4.6 times the CT rating.
