Description
GE 750-P5-G5-S5-HI-A20-G-E
Technical Specifications:
- Brand: General Electric (GE)
- Model: 750-P5-G5-S5-HI-A20-G-E
- Product Type: Multifunction Protection Relay
- System Platform: GE Multilin 750 Series
Functional Features:
- Comprehensive Protection: Integrates overcurrent, ground fault, thermal overload, and differential protection in a single unit.
- Advanced Metering: Provides high-accuracy voltage, current, power, and energy metering for power quality analysis.
- Customizable Configuration: The specific suffix string defines exact input/output options, communication protocols, and protection features.
Application Scenarios:
Medium-voltage motor protection, generator protection, and feeder protection in industrial power distribution systems.
Performance Parameters:
High-speed fault clearing with precise CT/VT ratio matching and wide dynamic range.
Material Composition:
Ruggedized metal enclosure, high-reliability solid-state components, and isolated analog/digital I/O.
Structural Characteristics:
Standard rack-mount or panel-mount form factor with a front-panel LCD display and navigation keypad for local configuration.
Working Principle:
Continuously samples AC waveforms, processes them through advanced protection algorithms, and initiates breaker trips when fault conditions are detected.
Installation Requirements:
Mount in a clean, dry environment. Connect CTs and VTs with correct polarity. Use shielded cables for all analog and communication inputs.
Precautions for Use:
Never open CT secondary circuits while energized. Use GE’s EnerVista software for configuration and firmware updates.
