摘要
通过查找4号发电机定子接地保护动作原因,对造成接地故障的2YH进行分析,检查不接地系统采用半绝缘PT造成的隐患,并提出应对措施。
According to find out the reason of 4# generator stator grounding protection action,the paper analyzes the 2YH caused grounding failure,and checks of the ungrounding system using semi-insulating PT caused hidden trouble,and proposes solutions.
