Abstract
According to the adaptive filtering theory
an adaptive filtering method using for on-line monitoring PD in transformers is presented. The adaptive filtering software that is used for on-line monitoring PD in transformers is programmed due to this method. The result of simulated experiment indicates that this method can efficiently suppress the external electromagnetic interference singals and improves the ratio of singal and noise.
