Space charge properties of PPLP insulation

Space charge properties of PPLP insulation
Space charge properties of PPLP insulation
The space charge accumulation in the lapped dielectric has been a concern as it may affect the reliability of the insulation. This study intends to investigate charge dynamics in the polypropylene and in the lapped sample with Kraft paper, with or without the impregnating oil. The space charge profiles were tested using the pulsed electroacoustic technique (PEA) under same DC electric field. Both ionization and charge injection have been found in Kraft paper. For the lapped samples, significant amount of charge has been found accumulated at the interface that has the same polarity as the nearby electrode.

Abstract

The space charge accumulation in the lapped dielectric has been a concern as it may affect the reliability of the insulation. This study intends to investigate charge dynamics in the polypropylene and in the lapped sample with Kraft paper, with or without the impregnating oil. The space charge profiles were tested using the pulsed electroacoustic technique (PEA) under same DC electric field. Both ionization and charge injection have been found in Kraft paper. For the lapped samples, significant amount of charge has been found accumulated at the interface that has the same polarity as the nearby electrode.
