Partial Discharges Activity within an Internal Void at AC Voltage Disturbed by High Frequency Components
Original language description
Frequent use of power electronics in electrical power systems imposes significant impulse and harmonic voltage stresses on various insulation systems. These systems are stressed by very fast and repetitive voltage distortions, which are superimposed on the power frequency voltage. The lifetime of an insulation system is influenced by partial discharge (PD) activity that is a consequence of long-term stresses or manufacturing imperfections. It has been proven that the intensity of PDs significantly depends on the operating voltage waveform. The paper deals with the experimental measurement of PDs on the physical model of an internal void in a solid dielectric under above mentioned voltage stress conditions. Gathered patterns and parameters of PDs were analyzed and evaluated to determine whether there exists any influence of higher harmonics content on the lifetime of the insulation system. The presented results show that the presence of high frequency oscillations on power frequency voltage have the impact on the PD activity. These findings can be significant for insulation lifetime assessment in the power systems containing power electronic devices.
