Product Details:

The GE SR750-P1-G1-S1-HI-A20-G feeder management relay is a high-performance digital protection and monitoring unit from GE Multilin 750 series, specially developed for medium voltage distribution feeders, substation and industrial power distribution systems. This feeder management relay integrates comprehensive feeder protection, precise electrical metering, breaker control and fault recording functions. It monitors phase current, ground current, bus voltage and frequency in real time, and executes multiple protection actions including overcurrent, directional overcurrent, overvoltage, undervoltage, overfrequency, underfrequency and breaker failure protection. As a stable multilin feeder protection relay, it is equipped with 8 programmable 4-20mA analog output channels, multiple digital input and output points for circuit breaker status monitoring and trip control. The front panel has backlit LCD display and operation keypad, with LED status indicators for operators to check real-time electrical readings, alarm events and fault waveform data conveniently. It supports multiple industrial communication protocols such as Modbus and DNP3, enabling data connection with SCADA and DCS systems for remote parameter setup and data uploading. The robust housing and conformal coated internal circuit boards protect electronic components against dust, moisture, corrosive gas and mechanical vibration in harsh substation environments. As an essential ge power protection relay, it is widely deployed in power plants, industrial substations, oil & gas and petrochemical power distribution projects. When the original relay suffers measurement deviation, protection malfunction or component aging, this replacement spare part can be installed to restore complete feeder protection and monitoring functions, isolate power faults rapidly and avoid large-area power outage of the power distribution system. Every relay undergoes full protection characteristic testing and communication verification before shipment to guarantee stable and reliable performance.
