Abstract The high voltage cable faults are classified by the way of cable fault location and the way of fault character, meanwhile the causes of the formation of faults are analyzed. General testing projects of cable condition are summarized, and the cable condition testing method and technique is contraposed to different types of cable faults. Precautionary measure of cable fault is proposed. From the perspective of the parts of cable fault, fault of the cable ontology accounted for a significant portion; In terms of forming reason, the equipment quality problems, bad design and construction technology, external force damage and the external factor are the three main reasons causing of cable faults; Cable operation inspection, partial discharge test, operation temperature monitoring are three most effective detection means which can early find the cable faults. Put forward the preventive measures of cable fault, production and design process should be strictly controlled. At the same time it should to strengthen the inspection and the on-line monitoring of cable and preventive measures. In this way the defects could be found before they cause cable fault.
