The HI 13 tandem accelerator at CIAE has been running for more than ten years since it was put into normal operation in august 1987. The accumulated operation time and beam time is about 40000 and 35000 h, respectively. The machine now is still in good technical condition with highest terminal voltage of 12.7 MV with beam and beam time of more than 3500 h per year in recent years. The completely home made laddertron for the machine has been in operation for near 8000 h with good performance. The original “blue...

The HI 13 tandem accelerator at CIAE has been running for more than ten years since it was put into normal operation in august 1987. The accumulated operation time and beam time is about 40000 and 35000 h, respectively. The machine now is still in good technical condition with highest terminal voltage of 12.7 MV with beam and beam time of more than 3500 h per year in recent years. The completely home made laddertron for the machine has been in operation for near 8000 h with good performance. The original “blue resistors” made by HVEC in the high voltage divider system of the HI 13 tandem accelerator have been completely replaced by the resistors with framework which are completely home made and the performances of the resistors are satisfactory. To meet the requirements of the experiments, five additional beam lines were built up in the past ten years making the total number of the beam lines in the laboratory up to eleven and some other improvements on the machine have also been done.

It is very important to accurately measure the wave form of fast transient voltage in high voltage apparatus experiments and elementary researching field of insulation materials. In ideal circumstance, the fast transient measured by a voltage divider system will be a wave form without any distortion, but merely a sampling sequence in digital sampling module whose extent value is divided according to the divider ratio. However, in the application of practical measurement, due to the poor quality of transient response of voltage divider system, the measured waveform of fast transient will be distorted after passing through the voltage divider system. The distortion of waveform caused by the poor quality of transient response of voltage divider system will be more serious when front chop impulse and steep-front impulse ismeasured. At the same time, the quantization noise which is produced by the digital sampling module of measured impulse wave form will greatly affect the exact measurement of the peak value of voltage and all time parameters will appear great inaccuracy. The reason why digital impulse voltage measuring system introduces some distortion in measured input impulse voltage waveform is analyzed .A new algorithm method, which uses noise reduction technique based on discrete Gabor expansion and incremental Wiener filter to achieve reconstruction of digital high voltage impulse waveform, is presented in this paper. It is noticed that there is different feature between the Gabor coefficient of fast transient and noise distribution in the time-frequency domain, the Gabor series method is presented for denoising the impulse signal embedded in noise. In order to recover the fast transient distorted by oscillation on the test circuit, this paper analyze the theory of deconvolution and present an incremental Wiener filter to perform reconstruction of digital high voltage impulse waveform. To verify the effectiveness of this algorithm, simulated waveforms obtained from IEC1083-2 TDG (test data generator) is calculated by this method. Calculation results show that this algorithm can denoise effectively and approaches high accuracy and stability, satisfying the needs of reconstruction of digital high voltage impulse waveform.
