The main requirement for overhead line and pantograph monitoring are accurate measurements within a high-voltage environment (15 – 25 kV). Optical sensors are passive elements, and as their measurement principle is based on light, no active excitation of the sensors is needed. That means that there are no interferences with other operations during measurement.
Optical technology is immune to EM and RF interferences, and is, therefore, the perfect fit for catenary and pantograph measurements. Where electrical sensors fail, or need advanced protection methods, optical measurements are still reliable, accurate and stable.
The focus of the measurements via a fiber optic sensing system is the lateral displacement of the overhead contact wire, the momentary vertical contact forces, and the detection of impermissible force peaks and loss of contact.
