The GE 750-P5-G5-D5-HI-A1-R-E-H is a microprocessor-based feeder management relay engineered by GE Multilin for comprehensive control and primary protection of distribution feeders. This member of the SR relay family combines advanced monitoring, precise metering, and flexible I/O within a single compact unit designed for continuous industrial operation. The 750-P5-G5-D5-HI-A1-R-E-H features an enhanced backlit LCD with intuitive menu navigation, a rugged drawout case for simplified maintenance, and specialized humidity-resistant conformal coating (the "-H" suffix). Supporting Modbus RTU and DNP 3.0 protocols, the 750-P5-G5-D5-HI-A1-R-E-H provides seamless integration into SCADA and DCS systems, delivering complete asset management and maintaining high reliability for electrical power networks.
Primary Feeder Protection – Main protection for distribution feeders in industrial and utility substations
Load Management – Load shedding and throw-over (bus transfer) schemes
Equipment Backup – Backup protection for transformers and transmission lines
Renewable Integration – Distributed Generation (DG) interconnect protection
Arc Flash Mitigation – High-speed fault detection for arc flash safety
Industrial Installations – Motor control centers (MCCs), switchgear, and process plants
Utilities – Medium-voltage distribution networks and renewable energy plants
Flexible Input Options: Phase CT inputs rated at 5A, plus 5A ground and polarizing inputs, the latter enabling advanced directional protection.
Rugged Drawout Construction: Chassis slides out without de-energizing the main panel, minimizing downtime during replacement.
Harsh Environment Protection: Conformal coating ("-H" suffix) safeguards electronics from humidity and corrosion.
High-Voltage Control Power: Wide-range input (88–300 VDC / 70–265 VAC) allows direct connection to station batteries or AC mains.
Onboard Annunciation: Eight configurable 0-1 mA analog outputs and a large enhanced backlit display simplify local monitoring.
Comprehensive Data Recording: Captures up to 32 power cycles for oscillography, plus data logging, event recording, and IRIG-B time synchronization for post-event analysis.
Protects Feeders: Constantly monitors current and voltage to execute overcurrent, earth fault, under/overvoltage, and frequency protection with programmable curves.
Monitors System Health: Performs high-accuracy metering of voltage, amperes, watt-hour costs, and frequency, storing up to 200 time-stamped events for diagnostics.
Captures Events: Records oscillography (up to 32 power cycles) and data logging for troubleshooting and commissioning.
Controls Remotely: Operates via RS485 serial or optional Ethernet ports with Modbus/DNP protocols.
Simulates System Responses: Built-in simulation mode and playback capability simplify end-to-end protection system testing and commissioning.
Q1: What do the suffixes (P5, G5, D5, HI, A1, R, E, H) in the 750-P5-G5-D5-HI-A1-R-E-H mean?
A1: P5 = 5A phase CT inputs; G5 = 5A ground CT input; D5 = 5A polarizing input (less common for directional element); HI = high-range control power (88-300VDC/70-265VAC); A1 = eight 0-1 mA analog outputs; R = enhanced display; E = EnerVista compatible hardware; H = conformal coating for humidity protection.
Q2: Can the 750-P5-G5-D5-HI-A1-R-E-H be used for backup protection of transformers and transmission lines?
A2: Yes. The 750-P5-G5-D5-HI-A1-R-E-H provides comprehensive backup protection for transformers and transmission lines at a reduced product life cycle cost.
Q3: Does the 750-P5-G5-D5-HI-A1-R-E-H have conformal coating and a drawout case?
A3: Yes and yes. The 750-P5-G5-D5-HI-A1-R-E-H includes humidity-resistant conformal coating (the "-H" suffix) and a full drawout chassis (standard for all 750 series units).
Q4: What communication protocols are supported by the 750-P5-G5-D5-HI-A1-R-E-H?
A4: The 750-P5-G5-D5-HI-A1-R-E-H supports Modbus RTU (via RS485) and DNP 3.0 level 2. An optional 10BaseT Ethernet port is also available for IEC 61850 integration.
Q5: Is the 750-P5-G5-D5-HI-A1-R-E-H still available? What is the recommended alternative?
A5: The 750-P5-G5-D5-HI-A1-R-E-H is discontinued. GE now recommends the Multilin 850 Feeder Protection System as the direct high-performance alternative.
