A tracking wheel ageing test system based on acquisition measurement system are developed. The design including sheave drive structure, current sensor, and current sheave drive structure and a leakage current principle of the tracking wheel test platform sensor protection circuit is presented, and the development of leakage current analysis software is developed based on. LabVIEWS.0. Shielded cable is used to replace all connecting lines, one end of cable shielding layer is grounded, and isolation transformer is adopted are presented, in order to avoid of interfered by background noise and external electromagnetic interference. The leakage current measurement system is verified, and the results show that this system is highly automated with stable operation of mechanism and reliable leakage current output. This study may benefit the further research of the tracking wheel ageing test of composite insulators.
