利用数字式局放测量系统获取了大量放电谱图和放电脉冲波形。
Using the digital PD measuring system, plenty of related patterns of discharges and discharge oscillograms are obtained.
由于局部放电脉冲波形是不规则的，显然，它们的频谱是不同的，这将导致在测量点上脉冲波形的畸变。
Since a partial discharge pulse waveform is irregular and the spectrum of each pulse is different, a pulse wave form will be distorted at the measuring terminal of the circuit.
设计了具有较宽频率响应范围的紧凑型测试电路，结合高速数字示波器TDS75 4c对油中的局部放电脉冲波形进行了测量。
A compact circuit with enough wide frequency response is designed and the high speed digital oscilloscope TDS754C is used to measure pulse current of Partial Discharge (PD).
