포켈스 센서를 이용한 부분 방전 측정 기술의 GITR 적용

Abstract

In this paper, a novel method has been proposed by use of HY-Pockels sensor for the detection of PD in GITR(Gas InsuJated Transformer) in order to improve reliability and to overcome the shortcomings of other techniques which are currently employed. For this work, different types of the test specimen, simulating the winding of the real GITR, have been designed and fabricated to generate the PD. And then, the detection of PD has been realized by conventional methods according to IEC 270 and also the proposed novel sensor as well. Afterwards, their results are well compared to understand the correlation between the nature of the defects in the winding and their PD pattern
