An investigation of DC contamination flashover phenomena of suspension insulators
ABSTRACT A description is given of the basic results of an investigation
into DC contamination flashover phenomena of suspension insulators. A
novel real-time system was developed that was capable of observing the
partial discharge arcs visually and the leakage current quantitatively.
Insulators were tested and the leakage current was analyzed, with the
result that the effectiveness of the system was confirmed
