Intelligent Algorithm Detects Compensation Capacitor Failure

In the future, the railway's information transmission will be through the wireless communications. The non-insulated track circuit is an important railway equipment in China. It is widely used. The track circuit fault diagnosis is an important guarantee for railway transportation safety. The compensation capacitor is an important component of the track circuit, which can effectively guarantee the transmission distance and the signal quality. In recent years, the fault diagnosis of the non-insulated track circuit is mostly focused on the fault diagnosis of the compensation capacitor. The method of capacitor failure points out the entry points, the advantages and disadvantages of each method, and provides reference and help for later scholars.
