So far,the ground fault protection systems are widely applied to enhance reliability and safety of distribution networks worldwide,however,there are still some pending problems,such as large residential current caused by ground fault and difficulties of detection for high impedance fault.Ground fault neutralizer(GFN)system is good at ground fault current compensation,fault point location and PD monitoring and control.Basic principal, functional characteristics,application and function extension of Swedish GFN whole compensation technology are introduced,which concludes GFN protection technology can reduce events of special transient faults at utmost. This paper is based on a patent:Publication No.CN 101164214 A;Application No.200680013014.0.
