Abstract :
There are three earth type in Low voltage distribution system .They all have advantages ,but have disadvantages .How to comprehensive utilize their advantages ,improve the reliability and continuity. There introduced a way of selective abscission of the single phase earth of the three-phase three-wire IT system as impulse earth type. Confirming the feasibility of the way through analyzing and the simulation.
