Sensys to supply pantograph monitoring for Swedish railways
First publishedon www.ITSInternational.com
Swedish traffic enforcement supplier Sensys Traffic has been awarded a contract worth US$0.4 million by the Swedish Transport Administration for the monitoring of train pantographs using its Automatic Pantograph Monitoring System (APMS).
APMS is designed to identify damage to pantographs and prevent overhead power wires being torn down. The system uses non-contact technology to analyse the condition of pantographs as the train passes at normal operating speeds up to 250 km/h. Once installed, the sensor is designed to operate without interrupting train traffic, including during maintenance a service periods.
When damage is detected, the detector sends an alarm via Ethernet or GSM/3G to central control for verification and further actions. An alarm is sent within minutes of the passing event.
