SPM Signaling Power Monitoring

With Signaling Power Monitoring (SPM) operators can find and fix power problems before performance is affected. Signaling systems represent a central safety relevant element in all railway systems.

The performance and reliability of signaling systems is dependent on the quality and availability of the power supply network that feeds them. Signaling Power Monitoring (SPM) offers rail operators the opportunity to remotely monitor power supplies. The measurement of parameters such as voltage, current, battery condition and insulation resistance provides valuable data to the rail operators. This enables a comprehensive diagnosis of problems that may occur in power supplies, which shortens response times and ensures optimum availability of the signal systems.
