Improving the reliability of railway electric systems and preventing electrical outages due to insulator flashover and insulation failure are difficult because of aging infrastructure and the lack of continuous monitoring of the state of the systems.

The TRB Transit Cooperative Research Program's TCRP Research Report 211: Guidebook for Detecting and Mitigating Low-Level DC Leakage and Fault Currents in Transit Systems provides specifications for sensors being tested in the field and outlines their capabilities and appropriate operating conditions.
