According to the analysis of spectrum for a series of the partial discharge pulse waveforms, the author proposed that the upper cutoff frequence of a detector should not be higher than 1 MHz and the bandwidth of the detector should not he too broad.

• 作者根据对局部放电脉冲波形的频谱分析,提出检测器的检测频率以低于1兆赫(1 MHz)为好,频带不宜过宽。
