Abstract

A new optical method for spatially resolved measurements of high electric field strengths in gas-insulated high voltage components is presented. The method utilizes the parity mixing phenomenon and the Stark effect in a trace gas (NH(3)) added to the insulating gas (SF(6)). The change in the optical properties of the trace gas when exposed to the electric field is probed using a CO(2) laser. Measurements on different electric field distributions have been made and compared to theoretical calculations using the finite element method. The use of the Stark effect is briefly reviewed, and methods for extending the range of measurements and further increasing the resolution are discussed.

摘要

本文提出了一种用于空间分辨测量气体绝缘高压部件中高电场强度的新光学方法。该方法利用了添加到绝缘气体（SF(6)）中的痕量气体（NH(3)）中的奇偶混合现象和斯塔克效应。当痕量气体暴露于电场时，利用二氧化碳激光探测其光学性质的变化。已对不同电场分布进行了测量，并与使用有限元方法的理论计算进行了比较。简要回顾了斯塔克效应的应用，并讨论了扩展测量范围和进一步提高分辨率的方法。
