PLC coupler for gas-insulated switchgear INGEPAC™ SR PG is a device that allows PLC communications coupling in gas-insulated switchgear cubicles. There is a version for up to 36 kV cubicles and another one with voltage sensor for up to 24 kV cubicles. INGEPAC™ SR PG coupler is suitable for broadband communications, being able to transmit and receive in the 1-32 MHz range. INGEPAC™ SR PG complies with the IEC 61869-1:2009 and IEC 61869-3:2011 standards. Every unit is individually tested to ensure its accuracy.
