The best location of AE sensors is analyzed by 3-D model. And then it is calculated by computer simulation. Then we analyzed AE hit features generated by PD in real time so as to validate our theory. These AE features were acquired by advanced equipment. And the results of AE PD measuring for power transformer in field are illustrated in this paper.
The sensitivity of frequency response on different frequency spectrums is analyzed by sensitivity analysis. And more analysis is simulated by computer. Then the relation of transformer parameters' changing when the winding deformed are figured out by analysis of capacitance and inductance. Furthermore, dependent on the statistics of winding deformation, the probability of different kind of deformations...
