GE Multilin 750-P5-G5-S5-HI-A20-R-E-H Feeder Management Relay

The GE Multilin 750-P5-G5-S5-HI-A20-R-E-H is a versatile feeder management relay that combines protection, metering, and SCADA communications. Featuring a 5A current input and high-range power supply, it offers a robust solution for monitoring and isolating faults in industrial power distribution networks.

Product Description

The GE Multilin 750-P5-G5-S5-HI-A20-R-E-H acts as a high-performance command center for electrical distribution feeders. This sophisticated relay leverages advanced microprocessor technology to unify protection, control, and metering functions within a single, compact chassis. By consolidating these capabilities, the unit eliminates the need for redundant standalone components, thereby streamlining the architecture of your switchgear lineup.

This specific “HI” power supply configuration empowers the relay to perform consistently across a broad spectrum of AC and DC voltages. Consequently, the device maintains full operational integrity even during severe system disturbances or voltage sags. To bridge the gap between field hardware and supervisory levels, the A20 analog output option transmits real-time electrical measurements directly to SCADA systems. This continuous data stream allows operators to monitor feeder load and asset health from a remote location.

Personnel interface with the relay via a professional-grade front panel or through industry-standard communication protocols like Modbus and DNP3.0. To ensure longevity in demanding environments, the rugged enclosure provides superior EMI/RFI shielding. This protective barrier shields sensitive internal circuitry from the intense electromagnetic interference common in high-voltage substations. By integrating the GE 750 series, utilities and industrial facilities accelerate fault isolation and significantly improve overall grid stability.
