Insulator leakage current and zero value detection device

The invention provides an insulator leakage current and zero value detection device comprising an insulation rod. The top of the insulation rod is provided with a clamping assembly for clamping two insulators arranged longitudinally. The insulator leakage current and zero value detection device also comprises a controllable joint assembly disposed between the insulation rod and the clamping assembly and used for adjusting the position of the clamping assembly, and a control assembly disposed on the insulation rod, connected with the controllable joint assembly, and used for controlling the clamping assembly to measure and store the current and the voltage between the two insulators and to mutually convert the current and voltage signals. In addition, a ground controller is installed on theground to send a wireless current signal or a wireless voltage signal to be measured to the control assembly and to receive a measurement result from the control assembly. The detection device is simple in structure and is e
