A new parameter for evaluating waveform distortion of partial discharge signals after de-noising

The causes and influences of the waveform distortion of the waveform distortion of an inverter with nonlinear load are analyzed.

Present theoretical computing method and synohronous sampling computing method of electric equilibrium parameters for waveform distortion system.

The peper systematically analysed the cause of wave form distortion of output voltage in inverse (DC/AC) change circuit and its condition of harmonic and approached the method of eliminating harmonic.

As the strain amplitude increased,no→obvious→decreasing even obsolescent wave form distortion in sequence were observed,which showed that stick→weak slip→stick/slip→strong/full slip even unsteady flow occurred between the melt and the wall.

This paper analyzes the key fault types of a SPWM inverter, then the results are substantiated by simulation study, and the aberrant waves of the fault types are obtained.

This paper analyses the effect of wave distortion on the rating value of an asynehronous motor,and discusses various problems caused by the wave distortion.

Traditional analytic solution is difficult to consider the influence of the damper circuit ,tooth-slot effect ,winding distribution on waveform, so the finite element method coupled circuit in time domain is employed in this paper to analyze voltage and current waveforms, and calculate line-voltage THD of straight generator.
