摘　　要：在双极可控电感 L0 的回路中 ,触发后产生不衰减的暂态过程 ,并表现为随触发角而变化的等效 (暂态 )电感L ,故可制作消弧线圈。在 L0 - C- R的振荡回路中 ,振荡过程分为次暂态和暂态两个阶段 ,而后者的等效电感就是上述暂态电感 ,据此可采用谐振法 ,分压法、两点法等几种方法确定电网对地电容In the bipolar controllable circuit with inductance Lo, the transient process is not damped and expresses itself as an equivalent (transient) inductance L, varied with the fire angles of thyristors. It can be used as an arc-extingushing reactor. In the controllable Lo^C~R circuit the oscillation process has two different (subtransient and transient) stages, in the latter case the transient inductance is equals to the former value L. According to this, some methods for measuring the network capacitance to ground are presented.
