运行经验表明，在电力系统各种故障中，单相接地短路占比很大，约占全部短路

运行经验表明，在电力系统各种故障中，单相接地短路占比很大，约占全部短路故障情况中的90％以上，两相短路发生较少，而三相短路的发生机率最低。虽然。如此，但是三相短路往往会带来最大的伤害，因为它的短路电流最大，发生故障后造成的影响也是最为严重的，必须给予足够的重视。

Operation experience shows that single-phase to ground short circuit accounts for a large proportion of all kinds of power system faults, accounting for more than 90% of all short-circuit faults, two-phase short circuit occurs less, and three-phase short circuit has the lowest probability. However, three-phase short circuit often brings the greatest damage, because it has the largest short circuit current and the most serious impact after failure, so we must pay enough attention to it.<br>
