Electrical railways that run on alternating current networks use a pantograph to connect the train to the electricity source—the catenary. The pantograph has a “contact shoe”, the metal conductor which draws the electricity needed to run the train. As the catenary is often shorted to the ground while the contact between the catenary and the contact shoe creates dust on the isolators, circuit breakers may trip several times per day.
These trips damage railway breakers and may lead to premature equipment wear. Refurbishing or maintenance operations on circuit breakers lead to repeated network shutdowns and railway operators’ revenue is affected.
By controlling the circuit breakers’ tripping operations with the SynchroTeq technology, the arcing time is minimized and the re-ignitions are avoided. Railway operators can improve their systems and take advantage of several other technical and economic benefits.
Benefits:
- Increases revenues by reducing system downtime
- Increases passengers satisfaction level due to the improvement of on-time performance ratio
- Decreases refurbishing and replacement frequency of critical assets
- Increases reliability of critical equipment and overall network
- Leverages the power of stored data to streamline operational and maintenance practices
Secure and reliable communication between safety signs and sensors is the most important aspects of road signaling, tower lighting system or water navigation signaling.
Interoperability between devices from different vendors and system reliability are amongst the most important qualities of a good and secure communication system. Relying on a robust and dependable system is a prerequisite when operating outdoors the whole year round under harsh temperatures and in extreme climates.

Electrical railway networks use voltage regulation equipment such as capacitor banks to ensure their system’s stability. Capacitive loads in railway distribution substations are switched on and off several times a day.
Therefore, inrush currents and voltage transients that result from capacitive load switching can cause serious damages on circuit breakers and reduce their lifespan. Over time, refurbishing or replacement of circuit breakers throughout the network may lead to frequent network downtime, reducing railway operators’ revenue and passengers satisfaction level.
The SynchroTeq technology gives railway operators the means to improve their systems and take advantage of several other technical and economic benefits. SynchroTeq controls a railway network’s capacitive loads by switching them at the optimal instant, which eliminates inrush currents and voltage transients.
Thanks to unique features such as fast switching, ability to handle partially discharged capacitor banks and more, SynchroTeq technologies improves responsiveness in voltage regulation adjustment.
Benefits:
- Increased revenues, owed to the reduction of system downtime and to circuit breakers reduced maintenance/repairs
- Leverages voltage regulation techniques
- Quickly adjusts voltage regulation through fast switching of capacitive loads
- Decreases refurbishing frequency of medium voltage assets
- Increases reliability of critical equipment and overall network performance
- Increases passengers satisfaction level due to the improvement of on-time performance ratio
Maintenance cost optimization, enhanced reliability and increased availability of HV & MV mission critical assets are amongst the greatest challenges of the industry.
Critical assets such as power transformers, circuit breakers, shunt reactors and capacitor banks are crucial to electrical power systems. Keeping these key assets operational as long as possible at a reasonable cost without impacting reliability, performance and network optimization is without a doubt one of the industry’s primary challenges.
To ensure system reliability, VIZIMAX offers monitoring capabilities such as a secure web based graphical user interface, a sequence-of-event recorder (SER), a user friendly human-machine interface, and a waveform visualizer.
VIZIMAX solution collects and monitors data from mission critical assets to improve the efficiency and reliability of electrical infrastructure.
These critical – yet hidden, scattered and unrecognized – data become visible and available in SCADA/DCS/PMS/DMS solutions, either in facilities or in central sites, in view of improving the efficiency and reliability of electrical systems, as well as anticipating critical failures and improving maintenance practices.
Benefits:
- Increases revenue by minimizing facility downtimes and product failure
- Leverages data for real-time access to health/status indicators and monitoring from assets to schedule and optimize the costs of refurbishments, maintenance or replacements
- Provides visibility on mission critical HV-MV assets
- Streamlines and reduces the costs of operational and maintenance practices
- Expands equipment lifespan and efficiency
- Increases production apparatus reliability
- Monitors critical assets, predict defaults and notify responsible personnel
- Provides real-time web monitoring and control
