Starting from voltage transformer working principle and insulator voltage distribution test principle, this paper raised a kind of insula-tor state test method based on distribution voltage test. Via measuring of insulator end umbrella skirt voltage and comparing with normal working insulator voltage, judgments were made to determine whether the insulator was damaged or not. The method is simple in operation with a little working quantity, being able to correctly and effectively test working conditions of insulators, which improves safe operation’s reliability of ex-press railway line.
