| Abstract: | Since the transformer wired by YynO and Dynl i in 10 kV distribution network is easy to disconnection at high, low voltage side, this paper analyzes the negative effect on distribution network brought by disconnection. The paper also propose to calculate the transformer performance by vector diagram and symmetrical component method and works out the change law of voltage and circuit to accurately judge fault, eliminate hidden danger and ensure the safe and reliable running of distribution system. |
