Abstract

Partial Discharge (PD) measurement on power transformers using Ultra-High Frequency (UHF) techniques has great advantages on IEC method including possibility of online application, localization and greater immunity against external noises. But lacking a method to calibrate or at least determine sensitivity of UHF method for power transformers is the main disadvantage of this method. Thus severity of PD detected by UHF method cannot be determined. In this paper, main parameters that affect the relation between severity of PD, defined by apparent charge of IEC method, and received signals by UHF method are investigated in detail using laboratory measurements and simulation tools. The purpose of paper is to investigate possibility of PD calibration using UHF probes by evaluation of amount of calibration error caused by each of the above parameters. Then, a method to estimate the minimum possible ratio between UHF signal and corresponding apparent charge is proposed based on the results obtained within investigation of calibration parameters.
