Product Description
Generator Resistance Cabinet High Voltage Generator Neutral Point Grounding Resistance Box
The generator resistance cabinet, also known as the generator neutral point grounding resistance cabinet, is designed for diesel generators or wind turbines operating in grid connection mode. It provides critical protection by detecting single-phase grounding faults, quickly switching circuits, and limiting grounding current to prevent overvoltage hazards and insulation damage.
Key Features and Benefits
- Prevents winding insulation damage and subsequent inter-phase or inter-turn short circuits
- Utilizes high-quality high-voltage resistors developed by Lonroy
- Features custom-designed functional structures for various working environments
- Safe operation with high temperature resistance and minimal resistance temperature coefficient
- Ideal for high-resistance grounding in 35KV and below generator sets
Applications
Widely used in urban power supply systems, power plants, subways, ships, metallurgy, wind farms, photovoltaic power stations, and ports.
