Paper Abstract

Static electrification and partial discharges caused by oil flow in power transformers lead to many accidents. This paper introduces an optical fiber sensor which can be directly mounted inside high-voltage electric devices for electrification measurement in power transformers. Unlike the existing normal electrification measurement method which only be used in static oil, the new one take optical fiber as its probe and measures the electrification in flowing oil by detecting luminous flux, and is available for on-line monitoring.
