In order to obtain partial discharge (PD) measurements under impulse voltage, a PD measuring probe based on a current transducer was constructed. In this paper, the transfer function of the current transducer was proposed, and bode plot simulated the effect of changing some of variables, then by selecting magnetic cores and optimizing chief parameters, a PD measuring probe has both wide bandwidth...
Partial discharge is defined by IEEE as an electrical discharge that only partially bridges the insulation between conductors and that may or may not occur adjacent to a conductor. Partial discharges occur when the local electrical field intensity exceeds the dielectric strength of the dielectric involved, resulting in localized ionization and breakdown. Therefore, measurement and analysis of this...
In order to study partial discharge pulses under impulse voltage effectively, a high-frequency current transducer for measurement of PD is developed. According to the equivalent circuit model, its principle and transmission characteristics are analyzed, and the effects of coil turns integral resistance and stray capacitance on frequency properties are studied. Moreover, calibration and analysis of...
