Abstract

In this paper, the authors analyze periodic interference in online PD wide bandwidth monitoring and its characteristics. A suitable method of rejecting periodic interference in online PD wide bandwidth monitoring through a direct wave trap filter is proposed. The principle and design methods are discussed. Experimental results are also given. The results prove the method be both novel and effective. In the filter process, it is possible to compress the data and to extract the characteristics value
