跑偏开关接触部分发热是由于压紧是弹簧或螺栓松动和表面氧化所致，通常发展很快。因为受热的影响接触部分更容易氧化，使其电阻增加，跑偏开关温度升高；若不断发展下去便可能会发生电弧，进而变位接地短路和相间短路。
双母线系统中，跑偏开关当一组线的隔离开关发热时，应将发热的隔离开关切换到另一组线路上去。若是单母线系统的隔离开关，则应减轻负荷；条件允许的情况下*好将隔离开关退出运行，如果母线可以停电应立即进行检修。跑偏开关因为负荷关系不能停电检修又不能减轻负荷时，须加强监视。如发现温度剧烈上升，应按规程的规定断开相应的断路器。
线路隔离开关接触部分发热时，跑偏开关其处理办法与单母线隔离开关相同，不同之处是该隔离开关有串联的断路器可以防止事故的发展，跑偏开关因此隔离开关可以继续运行，但需加强监视，直到可以停电检修为止。
