Abstract :
The insulators in power transmission lines should be inspected periodically to prevent power failure. By measuring their insulation resistance and distribution voltage with a high resistance resistor at each probe, the developed inspection tool can reliably and safely detect faulty insulators in an insulator string. We confirmed its effectiveness through live-line performance tests.
