Abstract:

It introduces the classification of current transformer and the open circuit hazard of secondary circuit. Combined with the open circuit event of current transformer secondary circuit at generator end of a 330MW unit in a power plant, the reason why the current transformer is prone to secondary open circuit is summarized. The precautions for solving such events are provided as reference for the operation and maintenance of current transformers with the same type.
