GE 750-P5-G5-S5-HI-A20-R-E Feeder Management Relay – GE Multilin 750 Series
When a feeder protection relay fails or goes missing in a medium-voltage distribution system, the consequences are immediate and severe: uncontrolled fault currents propagate through the network, breakers trip indiscriminately, and entire production lines or utility feeders go dark. Without a dedicated feeder management relay, engineers are left with no coordinated overcurrent protection, no earth-fault detection, and no real-time metering — turning a manageable fault event into an extended, costly outage that threatens both equipment and personnel safety.
The GE 750-P5-G5-S5-HI-A20-R-E is a fully specified variant of the GE Multilin 750 Feeder Management Relay, engineered for demanding medium-voltage feeder protection and control applications. Within the 750 Series product family — GE Multilin’s flagship feeder protection platform — this model integrates a comprehensive suite of protection, metering, and communication functions into a single 4U drawout chassis. The GE Multilin 750 Series is deployed across utilities, industrial plants, and infrastructure projects on every continent, recognized by protection engineers as a benchmark for dependable feeder management.

Key Features & Benefits
- Integrated Protection Suite: Combines overcurrent, earth-fault, directional, reclosing, and voltage protection in one relay — eliminating the need for multiple discrete devices and reducing panel space.
- High-Accuracy Metering: Built-in revenue-grade metering provides real-time and historical energy data without additional transducers, supporting energy audits and power quality analysis.
- Flexible Communications: Native Modbus RTU with optional IEC 61850 GOOSE messaging enables seamless integration into both legacy SCADA systems and modern digital substations.
- Drawout Design: The drawout chassis allows relay removal and replacement without disconnecting field wiring, minimizing maintenance downtime in live switchgear panels.
- Adaptive Reclosing (79): Configurable multi-shot reclosing logic restores supply automatically after transient faults, improving feeder availability for utility and industrial networks.
- Event & Fault Recording: Oscillography and sequence-of-events recording accelerate post-fault analysis and root-cause investigation.
- Cybersecurity Ready: Role-based access control and password protection align with NERC CIP and IEC 62351 requirements for critical infrastructure.
Industry & Equipment Applications
- Electric Utilities: Distribution feeder protection in 11 kV–33 kV substations; automatic reclosing for overhead line feeders.
- Oil & Gas: Motor feeder and cable protection in upstream production facilities and LNG terminals.
- Mining & Minerals: Protection of high-power feeder circuits supplying crushers, conveyors, and hoists in underground and surface mines.
- Water & Wastewater: Feeder protection for pump station MV switchgear; earth-fault detection in resistance-grounded systems.
- Pulp & Paper / Steel: Continuous process industries where feeder availability directly impacts production throughput.
- Data Centers & Critical Facilities: Selective feeder protection ensuring fault isolation without cascading outages in N+1 power architectures.
