摘要
在理论分析脉冲电流法和TEV检测法的检测特性的基础上,实验研究在模拟开关柜运行有电磁干扰的工况下,局部放电量pC值与TEV检测的dB值的关系,为现场开关柜局部放电检测和评价提供依据。
Based on the theoretical analysis of detection feature of pulse current method and TEV testing method, the relationship of pC value and dB value is discussed in the condition that simulation switchgear runs with electromagnetic interference, which gives standard for the switchgear partial discharge detection and evaluation.
