Abstract

Partial discharges (PD) occurring in high-voltage insulation systems can cause equipment failures and pose safety hazards. Commonly used techniques for detecting and characterizing PD activity, especially on the surface of insulation systems, include radio frequencies signal analysis and detection of ultraviolet radiation emissions. The aim of the research work was to perform a comparative analysis of the signals emitted by surface partial discharges in radio frequencies and the phenomena accompanying ultraviolet radiation emissions, as well as indicating possible directions for further basic research aimed at building a knowledge base and improving measurement methods. This paper presents an analysis of VHF, UHF and UV signals emitted by surface PD generated under laboratory conditions. The obtained results confirm that radio frequencies and UV signal analysis can provide important information about the activity and surface location of PD, including information on the intensity and nature of PD.
表面局部放电发射的射频和紫外信号分析
高压绝缘系统中发生的局部放电(PD)可能导致设备故障并构成安全隐患。常用的检测和表征PD活性的技术,特别是在绝缘系统表面,包括射频信号分析和紫外线辐射发射的检测。研究工作的目的是对无线电频率表面局部放电发出的信号和伴随紫外线辐射发射的现象进行比较分析,并指出进一步基础研究的可能方向,旨在建立知识库和改进测量方法。本文对实验室条件下产生的表面PD发射的甚高频、超高频和紫外信号进行了分析。得到的结果证实,射频和紫外信号分析可以提供PD的活性和表面位置的重要信息,包括PD的强度和性质的信息。
