The railway contact network has the only power supply and no backup lines. Once a fault or power outage occurs, it directly leads to train shutdown. Therefore, the railway contact network requires high timeliness for emergency response to faults. The railway catenary monitoring device is installed at both ends of the catenary power supply arm, using the principle of dual end traveling wave distance measurement to achieve precise fault positioning and identification of fault causes, effectively assisting in fault handling and quickly restoring power supply.

l Main technical indicators
