Research has focused on studying the adaptive simulation model for transformer windings and attenuation of ultra-high frequency (UHF) signals radiated by partial discharge (PD) located inside windings. The UHF signals propagation is simulated by XFDTD 6.5 software which is based on finite-difference time-domain (FDTD) method. The attenuation of UHF in plane board model usually used by most researchers...
Ultra High Frequency (UHF) Partial Discharge (PD) location method is based on the time differences of UHF electromagnetic waves from PD source to different UHF couplers. Measuring arrival time of UHF electromagnetic waves accurately is very crucial to PD location. But the diffraction of UHF passing through windings may result in attenuation and time delay, which may lead to failure to locating PD...
