| Abstract: | This paper analyzed the existing deficiencies and character of the neutral point earth for the ship power system,and brought forward a scheme which combined the characters of PTC and ZnO for neutral point earthed for ship power system to realize neutral grounding for ship.This kind of neutral grounding not only can limited the over voltage,but also avoid the use of rapid fuse.Meanwhile,the reliability of grounding was enhanced. |
