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
