Current sensor for installation on bushings


The ExxxR-xx current sensor is dedicated to installations on the bushing of gas insulated switchgear on the secondary energy distribution level. With a slim design, the holding system can be adapted to different kinds of T-connectors. Earthing can be done at the current sensor, through the shielding of the cable, or through the S2 connection inside the IED (intelligent electronic device).
