Abstract
This contribution focuses on verification of partial discharge (PD) localization for power transformers based on a novel curve fitting method. First part of this research was focused on checking the feasibility of the proposed localization algorithm published in 2018. This paper as a validation of the mentioned method uses measured partial discharge signals with high frequency current transformer (HFCT) and processed them using a curve fitting (CF) method with a high rated fitting quality. The extracted coefficients of the selected function terms are then evaluated in order to find the PD location. The proposed method is implemented on the high voltage winding of a lab transformer to verify its applicability and accuracy. The experiment is comprised of injecting PD pulses into different points along the test winding and applying the proposed localization algorithm. The proposed method is based on analysing the PD waveforms, which could be obtained from two sides of the high voltage winding of power transformers using high frequency current transformers. The curve fitting coefficients method and complementary measured results are presented and discussed comprehensively in this part of research.
