| Abstract: | It is very important to study the methods of noise suppression for on line monitoring partial discharge,which is based on pulses current detection in transformer.Both suppressive methods of continuous sinusoidal noise,periodical pulse shaped noises and stochastic pulse shaped noises are introduced in details and their advantages and disadvantages are discussed also.Finally,some advice is given. |
