GIS特高频局部放电传感器接收性能测试方法研究

Measurement methods research on receiving capacity for GIS UHF partial discharge sensor

提出用等效高度表征特高频局部放电传感器接收性能的测试方法,并建立专用试验测试平台,对传感器的接收性能进行检测,同时研究了两个不同厂家的特高频局部放电传感器的接收性能,分析了屏蔽对测试结果的影响。

In order to detecting the receiving capacity of ultra high frequency （UHF） partial discharge （PD） sensor, this paper proposes a method of ultra high frequency partial discharge sensor receiving capacity in height equivalent, establishes a special test platform and validates the design to detect sensor receiving capacity. Meanwhile the paper researches two sensors from deferent manufacturers and the impact of shielding on test results .
