Abstract
This paper provides the results and analyses of investigations into porcelain suspension insulators failures on the KEPCO system. The high failure rate of suspension insulators on distribution lines has been attributed to the volume expansion of the cement, the insulation puncture breakdown of the porcelain and the power arc failure. The utility must use only the good insulators and at least reduce the insulator failure rate. So, this paper recommends that the utility make test criteria(cement expansion test, steep front-of-wave flashover voltage test and power arc test. etc) on the suspension insulators.
