摘要
本文就GIS内部局部放电的超高频响应特性进行了试验研究,并进行了理论计算。本文还就获取信号方式进行了探索,提出了两个可供带电监测的获取信号的方法。
Measuring the Very High Frequency (VHF) signals from partial discharge in GIS is a sensitive, effective measurement to detect the intensity of the discharge. This paper presents the experiment research work on VHF detecting methods and analyses the response characteristic within the GIS chambers- Useful conclusions are obtained.VHF noises are fairly low at site and detecting PD from VHF signals has excellent sensitivity and high signal to noise ratio (S/N). This method will be very useful and practical in on-line monitoring.
