Ring-Type Current Sensor ExxxRG

APPLICATION

The ExxxRG current sensor (LPCT) is a non-conventional passive ring type sensor dedicated to installations on the bushing of gas insulated switchgear on the secondary energy distribution level. Its slim 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).

PRODUCT ADVANTAGES

• Passive technology – no active parts are inside, and no power supply is needed
• Easy installation on bushings and cables
• Slim ring geometry for installation in confined switchgear compartments
• Correction factors for amplitude and phase inaccuracy improve the sensor class
• Available as ECO version: Initial accuracy class 0.5, uses correction factors to improve the accuracy class to 0.2
• IP67 protection if needed
