We Export, Distribute, Trade, and Supply the best quality range of Relays including Reyrolle 7PG2111 Solkor Relays in Navi Mumbai, Maharashtra, India. The 7PG21 is a three-phase unit differential protection used to detect in-zone phase and earth faults. The relay is applied to the overhead line and underground cable circuits as well as shorter circuits such as interconnectors.
Relays (and associated CTs) are installed at each end of the protected circuit and connected with dedicated metallic pilot wires.
This established protection system provides a simple, robust protection of proven performance facilitating straightforward installation, commissioning, and maintenance.
Relays have 3 current inputs and are housed in E6 cases.
Additional relays and components can be added to the basic protection to provide:
1.Increased insulation level
2.Pilot Wire Supervision to monitor the integrity of the pilot circuit.
