Abstract
Adopting resistance grounding at neutral points of power grid is an important way to improve reliability and prevent false protection when fault current burning fault points at instant grounding. To classify by load types, i.e. important loads using high resistance grounding, can constantly operate 2 hours at single-phase grounding to avoid losses caused by sudden power cutoff. Secondary loads use low resistance grounding to rapidly cut out of faults.关键词
