So far, it is not very clear why the delayed postarc restrikes occur. In this thesis, two kinds of restrikes have been discovered through prebreakdown current measurment and analyses,(1) the abrupt breakdown, it is characterized by a suddenly appeared, with a period of a few microsecond prebreakdown current, it is initiated by particle. This kind of restrikes can be reduced by decreasing loosly adhesive clumps which drop into the gap after arc extinction.

弧后延时重击穿的起因尚不清楚，本文通过对预击穿电流的测试和分析，发现这种重击穿主要有两种类型：（1）突发性的击穿类型，其特征是击穿前看不到预击穿电流的增长过程，预击穿电流的形成只有数微秒时间，这种击穿是由颗粒引起的，减少大颗粒脱落可以降低这种击穿的几率。

Moreover, second-winding current waveform of a current transformer is calculated under the transient current of the typical short-circuit fault by numerical method. The analysis shows that the relevant protection equipment may refuse to trip when the fault current is extra high. It will result in the maloperation of protective relays for loss of their selectivity, and cause other protective relays to operate beyond range, and extend the scope of shutdown of power supply.

在这些回路出口处发生相间直接短路等严重故障时，流过相应TA一次侧的故障电流可能达到TA额定工作电流的100倍以上，大大超过了保护用TA的10%误差容许倍数，将使TA严重饱和，从而影响相关的保护设备的动作性能，因此有必要对在这种特大电流作用下的TA的传变特性做一些探讨，以分析其对继电保护装置动作特性的影响及应采取的措施。
