Breakdown prediction modelling of PP with different crystal morphology insulation under HVDC
Breakdown prediction modelling of PP with different crystal morphology insulation under HVDC
A 3-phase breakdown model has been developed to study the impact of different crystal morphologies of PP insulation on its breakdown behaviour under HVDC stress. The model considers the results of previous research where a mesophase has been observed in addition to crystalline and amorphous phases in thermal treated polypropylene film. The parameters for the three phases in the model have been tuned based on the experimental breakdown results. The model can provide a useful tool to investigate the breakdown behaviour of polymeric insulation and facilitate the design and development of more reliable insulation materials for HVDC applications.

Abstract
A 3-phase breakdown model has been developed to study the impact of different crystal morphologies of PP insulation on its breakdown behaviour under HVDC stress. The model considers the results of previous research where a mesophase has been observed in addition to crystalline and amorphous phases in thermal treated polypropylene film. The parameters for the three phases in the model have been tuned based on the experimental breakdown results. The model can provide a useful tool to investigate the breakdown behaviour of polymeric insulation and facilitate the design and development of more reliable insulation materials for HVDC applications.
