Abstract: The on-line detective apparatus’ principle and quality is analized, which can measures the electric field strength of every insulator on line among a chain of insulators directly in order that the quality of the insulator is verified. On this basis, a novel on-line detective apparatus is designed, and its system structure, software structure, hardware structure and key technology are described in detail. It has been proved that it illustrates a good prospect of application and high practice value.
