Abstract

JDBH type of small grounding current system for harmonic elimination

over voltage protection and the sense of electrical protection

is one used for the non direct ground neutral system.When the single-phase grounding fault is occured

with parallel shunt as its principle

the device will cause the fault phase directly connect the grounding grid

realizes the parallel shunt

voltage clamp

fault arc extinguish and implementation on the human body and equipment protection.Moreover

this paper introduces the basic principle of the device

its function and characteristics.
