Description

GE 760-P5-G5-S5-HI-A20-R-E

Technical Specifications:

  • Brand: General Electric (GE) Multilin
  • Model: 760-P5-G5-S5-HI-A20-R-E
  • Current Inputs: 5 A phase current, 5 A zero-sequence current, and 5 A sensitive ground current.
  • Power Supply: Universal power supply accepting 88-300 VDC or 70-265 VAC at 48-62 Hz.
  • Analog Outputs: Eight 4-20 mA isolated analog outputs.

Functional Features:

  • Comprehensive Protection: Provides primary and backup protection for feeders, including overcurrent, undervoltage, and directional overcurrent protection.
  • Advanced Monitoring: Features built-in oscilloscope, waveform capture, and actual value metering for detailed system analysis.
  • Data Recording: Continuous data logging with trend analysis, plotting, and export capabilities via the EnerVista 760 software.

Application Scenarios:
Widely deployed in utility substations, industrial power distribution networks, commercial building power systems, and renewable energy integration points.

Performance Parameters:

  • Communication Protocols: Supports Modbus RTU, Modbus TCP/IP, and DNP 3.0 over RS232, RS485, and 10Base-T Ethernet interfaces.
  • Processing Speed: Fast fault detection and relay tripping times to minimize equipment damage and system downtime.

Material Composition:
Housed in a rugged, flame-retardant industrial enclosure with high-quality copper busbars and gold-plated relay contacts for long-term reliability.

Structural Characteristics:
Standard rack-mountable form factor featuring an enhanced, wide LCD display, a red breaker-closed LED indicator, and intuitive navigation buttons for local operation.

Working Principle:
Continuously samples voltage and current waveforms via internal ADCs. The microprocessor runs real-time algorithms to detect fault conditions and executes predefined logic to trip circuit breakers or send alarms.

Installation Requirements:
Must be securely mounted in a standard 19-inch panel. Current transformer (CT) and voltage transformer (VT) secondary wiring must be correctly polarized and properly grounded.

Usage Precautions:
Always use the EnerVista software for configuration changes. Ensure CT secondary circuits are never left open while the relay is energized to prevent hazardous high voltages.
