| Abstract: | According to the conditions of drop-fuse used in some 35 kV power substations of countryside, phaselacking fault characteristics are analyzed and a protection criterion is proposed in this paper. The transformer protection is composed of phase-lacking, over loading and two zones backup over-current protections. |
