Abstract

1 Abstract: The development of a wideband partial discharge detector has been described The bandwidth of the detector's amplifier is 50 MHz and the lower cutofl frequency is 2.7s MHz The detector's ourput signal is processed digitally using the discrefe wavelet transform Threshold de-noising has been used to aaenaate the background noise. The detector is able to distinctly Characterize corona andpartial discharge pulses.

传统局部放电测量系统的阻抗检测与数据采集

摘要:介绍了一种宽带局部放电检测器的研制，该检测器的放大器带宽为50 MHz，下截止频率为2.7s MHz，检测器的输出信号采用离散小波变换进行数字处理，并采用阈值去噪来消除背景噪声。该探测器能够清晰地表征电晕和局部放电脉冲。
