MONITORING UNDERGROUND CABLE CONDITION UTILIZING THIRD HARMONIC CURRENT

Power failure in a power system caused by unscheduled cable failure may give significant problem to the utility company and to the consumers. This unscheduled cable failure can be overcame by periodically monitor the cable condition. There are many ways to monitor cable condition such as visual insp...
