提出了一种利用现场测试结果分析基于超高频 (UHF) 测量的局部放电 (PD) 信号的新技术。来自同时活动的放电源的信号可以根据其原点进行映射，从而简化对相位分辨放电模式的解释。该方案有可能实现对电力变压器和其他金属包覆高压设备中多个放电源的自动定位和跟踪。
A new technique for analyzing partial discharge (PD) signals based on ultra-high frequency (UHF) measurements is presented, using results from site tests. Signals from simultaneously active discharge sources can be mapped according to their point of origin in a manner that will simplify the interpretation of phase-resolved discharge patterns. The scheme has the potential to allow automated location and tracking of multiple discharge sources in power transformers and other metal-clad high-voltage plants.
