Abstract: Aiming at the problems such that failures happen frequently and it’s difficult to repair with outage during the process of overhauling high-voltage isolators in open air, this paper analyzed the live working of high-voltage isolators and the reasons of frequent failures. Combined with the practical application examples of the live working of high-voltage isolators, this paper pointed out several key problems of the live working, raising the corresponding countermeasures, which improves the reliability of equipment operation and grid power supply.
Key words: high-voltage isolator; failure; live working; repair with outage
