摘要
针对局部放电在线检测中比较严重的周期性干扰信号，提出一种数字滤波的抗干扰措施，介绍了该滤波器的基本原理和实现方法。
A new anti-interference technique of digital filter is presented for suppressing continuous periodical signal which is a quite serious interference in on-line PD measurements. The fundamental principle and realization of this digital filter is also introduced.
