This is a microprocessor‑based intelligent electronic device (IED) integrating protection, control, metering, monitoring and fault recording for medium‑voltage distribution feedersGE Vernova.
GE Multilin 750‑P5‑G5‑S5‑HI‑A20‑G‑E Feeder Management Relay
Protection Functions
- Phase Overcurrent Protection: Directional / non‑directional time‑delayed & instantaneous phase overcurrent, cold‑load pickup logicGE Vernova.
- Ground & Sensitive Ground Fault Protection: Directional ground overcurrent, sensitive ground fault, restricted earth fault for high‑impedance ground‑fault detectionGE Vernova.
- Voltage Protection: Overvoltage, undervoltage, neutral overvoltage elements.
- Frequency Protection: Under‑frequency, frequency decay for load‑shedding application.
- Reverse‑Power Protection: For distributed‑generation interconnection anti‑islanding protection.
- Negative‑Sequence Overcurrent: Detects phase unbalance faults.
Control Functions
- Circuit‑breaker remote / local open‑close control, breaker status monitoring.
- Synchro‑check for bus transfer; automatic bus transfer logic.
- Programmable logic for interlocking, load‑shedding schemes.
Metering & Monitoring
- Real‑time measurement: current, voltage, active/reactive power, power factor, energy kWh/kvarh.
- Fault event recording, oscillography capture, trip‑counter, alarm logging.
- Eight channels of 4‑20 mA analog outputs to transmit analog values to external SCADA systems.
Communication
Supports Modbus RTU, DNP3 serial protocols for data exchange with control host, configured via GE EnerVista software suiteGE Vernova.More products: www.plcva.com
3. Applications
- Utility Substation Distribution Feeders: Primary main protection for medium‑voltage MV feeders in power‑utility substations; backup protection for busbars and distribution transformersGE Vernova.
- Industrial Power Plants & Heavy‑Industry Plants: Petrochemical, metallurgy, mining large‑factory MV switchgear; protects critical production power‑supply circuits, isolates faults to avoid plant‑wide shutdown.
- Distributed‑Generation Interconnection: Grid‑connection protection for on‑site generators, solar / wind distributed generation, anti‑islanding protection.
- Commercial Large‑Scale Campus & Building Power Systems: For internal medium‑voltage distribution network feeder protection and automation control.
- Retrofit of Legacy Power System: Widely used for upgrade & replacement of old‑style electromechanical relays in existing switchgear panels, panel‑mount installation inside MV switch‑cabinets.
