Contact Line Measuring System (OVHWizard) has successfully delivered to SPL Austria by our partner, Dr. Wehrhahn. The system is installed on a trolley instead of a railway vehicle to support more flexible inspection of overhead contact lines.

As a solution to a complete measurement of contact wires of the Gotthard tunnel, Contact Line Measuring System (OVHWizard) is delivered successfully to Switzerland by our partner, Dr. Wehrhahn.
Contact Wire Measurement System can be used in two ways: (1) Stationary or in a fixed position and (2) installed on a rolling stock and inspect during movement.
Overhead Line Monitoring System can be equipped with a vehicle compensator to ensure high precision and accuracy during movements.
Contact line measuring system (OVHWizard) can operate reliably in various weather conditions, including sunlight, rain, or fog.
Overhead Contact Line Measuring System can inspect up to 4 wires simultaneously.
Overhead Line Monitoring System or OVHWizard can operate for 8 hours continuously.
Contact Line Measuring System, also known as contact wire measurement system or overhead line monitoring system, is a non-contact device used to inspect height, stagger, and uplift of overhead lines. This system can typically be used whether stationary or installed on a rolling stock during movements. To ensure the maximum accuracy of inspection, a vehicle suspension compensator can be integrated, using two types of laser-based sensors (depending on the vehicle).
Overhead contact line measuring system is equipped with ultrasonic sensors, transferring high-frequency ultrasonic waves to the overhead contact lines to detect the potential defects and failures. ADOR Tech’s overhead line monitoring system (OVHWizard) is integrated with five high-accurate ultrasonic sensors, offering a precise inspection at maximum speeds (1 kilometer in 6 minutes at measuring range of 10 centimeters or measurement points).
ADOR Tech’s overhead contact line measuring system (OVHWizard) is an accurate ultrasound-based device used to measure the position of overhead lines efficiently and reliably. Designed compact and lightweight, this system provides quick installation and straightforward application. Our Contact line measuring system provides both usage of fixed-position and vehicle integrated. Equipped with vehicle suspension compensator allows for automatic accurate measurement even in movements. Moreover, OVHWizard is engineered with Wizard Software, enabling the system to provide online visualization of inspection and post-processing data analysis.
