3.1.6 AC CURRENT TRANSFORMER INPUTS
Each AC current input has an isolating transformer and an automatic mechanism that shorts the input when the module is
withdrawn from the chassis. There are no internal ground connections on the current inputs. Current transformers with 1 A
or 5 A rated secondary current may be used.
CAUTION: VERIFY THAT YOUR RELAY MODEL CORRESPONDS TO YOUR RATED SECONDARY CURRENT.
UNMATCHED CTS MAY RESULT IN EQUIPMENT DAMAGE OR INADEQUATE PROTECTION.
The exact placement of a zero sequence CT, so that ground fault current will be detected, is shown below. Twisted pair
cabling on the zero sequence CT is recommended.
