绝缘液体的雷电冲击击穿电压的测定方法

[中文适用范围]： 描述了两种测试方法 A 和 B，用于评估绝缘液体在受到标准雷电脉冲时在发散场中的电气强度。方法 A 基于步骤程序，旨在提供脉冲击穿情况的估计 [外文原描述]： Describes two test methods, A and B, for assessing the electric strength of insulating liquids in a divergent field when subjected to standard lightning impulses. Method A is based on a step procedure intended to provide an estimate of impulse breakdown voltage under specific conditions. Method B is a statistical test designed to check a hypothesis about the impulse breakdown probability of an insulating liquid at a given voltage level.
