Abstract :
In this paper Mie scattering theory is used to analyze the angular scattering characteristics of defects in polyethylene insulation. It has been found that there is the distinct difference of scattering intensity among the black particles, microvoids and semi-transparent particles, in the ranges 8o ~20o and 60o ~80o angular windows. This deduction has been proved by experiment and it provides a sound basis for developing the laser scanning detection instrument which can be used to detect and to discriminate the dimension and type of the defects in XLPE insulation of HV and EHV cables
