Combined Diagnosis Study for Terminal Main Insulation Hole Defect in 10kV Cross-linked Polyethylene Cable

摘要

In order to study the main insulation of cable terminal hole defect, using visual detection, infrared imaging spectrometer, ultraviolet imaging instrument and pulse current method for the defects of various means such as joint detection. The experimental results show that several ways in which judge cable terminal hole defects that is feasibility, reliability and validity.
