Contact Wire Wear Measurement System, also known as contact wire thickness measurement or railway catenary inspection system, is a non-contact, laser-based device used to measure wear and thickness of overhead contact wires. This system is integrated into an existing pantograph and inspects contact wires continuously during vehicle movements. Engineered to inspect both single and double contact wires, this system provides an efficient measurement of different types of overhead wires, even twisted ones.
In electrified rail systems, the integrity of overhead lines is mission critical. These wires must maintain precise contact with pantographs to provide consistent electrical power to trains. Over time, as pantographs repeatedly glide along these wires to draw current, the contact area begins to erode. These wears can compromise electrical performance, introduce safety hazards, and escalate maintenance costs if left undetected. The most common issues that arise from the contact wire wear are voltage instability, current collection efficiency reduction, overhead wire breakage, and increasing carbon buildup on pantographs.
Catenary Wire Wear Measuring System (CatPro) can efficiently be integrated with our Contact Line Measuring System (OVHWizard) to be capable of measuring wear and thickness as well as wire profile and geometry. When paired, these two systems provide a complete view of the overhead contact system’s health, enabling predictive maintenance, real-time alerts, and trend analysis over time.
Railway catenary inspection system is a solution to measure wire wear and profile. Due to the whether conditions of Canadian railway and transit network, it is necessary for the contact wire wear measurement system to efficiently operate in different situations. Moreover, this system can prevent costly emergency maintenance, minimize service disruptions caused by unexpected wire failures, extend the life of the overhead contact systems through early intervention, plan renewals with data-driven insights, reduce manual labor and track occupation time, and ensure compliance with safety regulations and asset health standards.
