The Ground Fault Neutralizer (GFN) from Swedish Neutral once set the original standard for REFCL. It detects and locates Earth Faults with class leading detection and locating sensitivity.
REFCL is used for wildfire mitigation purpose in the USA and bushfire mitigation purpose in Australia.
The GFN eliminates the Earth Fault current utilizing power electronics (RCC) faster than a breaker can trip the fault.
Specifications
- EF Impedance detection and localization: 0-25kΩ
- EF Current kept below this level for earth fault locating purpose: 500 mA
- EF Current eliminated within: 85ms
