Abstract

In case of stator windings in 6.6 kV high voltage rotary machine, the pulse resonance shows in 1.1 MHz - 2 MHz and 20 MHz - 200 MHz as the range of low frequency. Actually, the peak of partial discharge appears the range which generated resonance frequency, and is confirmed in the range of 1.1 MHz -2 MHz. In this paper, the Sierpinski triangle fractal sensor have designed by using the CST MWS for confirming the partial discharge in 20 MHz - 200 MHz. As a result, we have obtained the result that the resonance pulse freqency is correlated with the partial discharge freqency in 20 MHz - 200 MHz.
