GE Multilin SR750-P5-G5-S5-HI-A20-R: High-Performance Substation Protection

The GE Multilin SR750-P5-G5-S5-HI-A20-R is a premier microprocessor-based Feeder Management Relay designed for the complete protection, control, and monitoring of medium and high-voltage feeders. As part of the highly reliable SR (System Relay) family, the 750 provides a versatile solution for utility substations and industrial power distribution systems worldwide.

This specific configuration is built for maximum sensitivity and reliability. With dedicated 5A Phase, Ground, and Sensitive Ground inputs, combined with high-range control power and redundant communication, the SR750-P5-G5-S5-HI-A20-R ensures that your distribution network remains stable, even under the most complex fault conditions. It is the definitive choice for engineers who require precision metering and advanced logic in a single, durable package.

Key Features & Operational Role

Substation Capability	Grid Stability Benefit
Triple-Layer Sensing	Combination of P5, G5, and S5 inputs detects everything from massive phase faults to small high-impedance ground leaks.
Redundant Serial (R)	Engineered for critical infrastructure. Redundant RS485 ports ensure SCADA visibility even if one link is severed.
Universal High-Range Power	Handles broad voltage fluctuations common in industrial grids; supports both DC battery banks and AC auxiliary power.
Advanced Waveform Capture	Captures oscillography data during faults, allowing for detailed "Post-Mortem" analysis to prevent future outages.
FlexLogic™ Customization	Enables automated bus transfer or load shedding without the need for an external PLC.

Frequently Asked Questions (FAQ)

Q1: What is the significance of the "S5" (Sensitive Ground) input?

A: The S5 input is designed for high-accuracy detection of low-level ground faults, vital in systems with high-impedance grounding where standard ground CTs might not trip.

Q2: Can I use this relay for motor protection if I don't have a 469?

A: While the 750 has overcurrent functions, it lacks the specialized thermal models and RTD management of the 469. It is always recommended to use the 750 for feeders and the 469 for motors.

Q3: Is the "R" communication option compatible with Modbus?

A: Yes, the redundant RS485 ports support Modbus RTU, allowing for seamless integration into most SCADA and DCS environments.

Q4: How fast can you deliver for a substation outage?

A: We prioritize "Grid Failure" situations. Express air freight typically delivers to major industrial centers in 3–5 business days.
