Research on insulation defect localization technology of power equipment

Insulation plays an important role in power system. During the production and operation of power equipment, there will inevitably be insulation defects occurring. Realizing the detection and localization of these defects is of great significance to ensure the safe and stable operation of power system. In this paper, different defect localization algorithms are proposed for transformer, cable and whole substation equipment, respectively. Experimental results show that these algorithms can reach a high localization accuracy.
