| Abstract: | The various noises in the on-line PD detection of transformers are listed and the disadvantages of different reduction measures are analyzed. A new measure is proposed to reduce the noises. A set of directional sensors is designed and the characteristics are tested in the laboratory. A good response to the PD signals and a big attenuation of the noises are obtained by the tests. |
