2016年4月，某变电站主变检修恢复送电时，对1号主变充电时，未退出220kV线路（主二保护屏）“15LP14（PSL631A）充电过流保护投入”、“15LP2（PSL631A）充电及过流保护跳闸”两块压板，导致220kV断路器充电保护躲主变励磁涌流而造成220kV线路断路器跳闸。
2017年3月31日，某220kV变电站220kV断路器保护（CSC-122B）的“过流保护跳闸出口Ⅰ”和“过流保护投入”两个过流保护压板处于投入状态，在线路复电完成后，开展对侧电厂的主变复电时出现励磁涌流，过流保护（断路器保护过流Ⅰ段）动作出口跳闸。
6 kv and above cable joint: (1) installing a cable terminal head, must be stripped semiconductor electric shielding layer, operation shall not damage the insulation, should avoid mark uneven situation, when necessary use sand paper to grind; The shield end should be flat and the graphite layer (carbon particles) should be clean. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, avoid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and sheath and other accidents. It is required to use my tinplate to braid copper wire for grounding lead. When connecting with the cable copper belt, it should be welded with chromium-iron tin. The shield of three-phase copper tape should be connected with ground wire respectively. Note that the shielded ground wire and steel armor ground wire should be separately drawn out and insulated from each other. The position of the welded ground wire should be as low as possible.
