Robust, Accurate and Stable Optical Technology

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.

HBK's Fiber Bragg Grating (FBG) Pantograph Measurement System ensures:

Detection of the contact force relief on the pantograph
Measurement of the sideways movement of the contact wire
Detection of undesired peaks in contact force
The possibility of integrating all performed measurements with GPS for location
Continuous 24/7 operation with the definition of thresholds and triggering of instantaneous alarms when a critical condition is detected
Certified for fire safety with EN 45545
Compliance with EN 50317 (standard for measuring the pantograph contact line interaction)
Minimum influence in vehicle maintenance by using standard contact strips
