Corona-type partial discharge detection in power transformers using fiber bragg gratings
##plugins.themes.academic_pro.article.main##
Abstract
We present a Fiber Bragg Grating (FBG) based scheme for sensing corona discharges in a power transformer. The corona-induced acoustic emissions detected using the FBG sensor pasted in a test cell is found to be correlated to the signals detected by HFCT sensor. A detailed spectral analysis of the detected signals is presented and the influence of electrode gap on the acoustic spectrum is investigated.
