PURPOSE:To house the main circuit equipment of a generator in a one-piece box and at the same time eliminate the need for a neutral point side cable of the generator. CONSTITUTION:A current transformer 4 for measuring neutral point side and a neutral point grounding device 5 connected to a generator neutral point side and a current transformer 2a for measurement and a surge absorber 2b connected to a generator line side are housed in one-piece box and at the same time the box is installed being adjacent to the generator, thus reducing installation space and the neutral point side cable of the generator. |
