PCS-9613 Differential Relay
The PCS-9613 relay is a current differential protection and overcurrent protection, control and monitoring unit with auto-reclosing function for distribution feeder lines in solidly grounded, impedance grounded, Peterson coil grounded and ungrounded system.
This relay can fully support the IEC61850 communication protocol and GOOSE function, and can completely meet the demands of a modern digitalized substation.
