About This Course

Stray currents are an invisible threat to electrified rail systems. They accelerate corrosion of tunnel reinforcement, degrade concrete slabs, and compromise signalling reliability. Left unchecked, these currents lead to catastrophic failures, costly repairs, and safety hazards. This course provides a practical, standards-aligned approach to monitoring and controlling stray currents in DC and AC systems.

Participants will learn how to install and calibrate sensors, set thresholds based on corrosion risk models, and interpret monitoring data for preventive action. The course covers EN 50122 and IEEE guidelines for stray current control, instrumentation selection, and SCADA integration for real-time alerts.

Key benefits include:

·        Compliance assurance: Meet EN and IEEE requirements for stray current monitoring.

·        Risk reduction: Prevent structural degradation and signalling interference before they escalate.

·        Cost optimisation: Shift from reactive repairs to predictive maintenance strategies.

·        Operational reliability: Maintain safe and stable electrification systems across tunnels, stations, and open track.

Through real-world examples and scenario-based reasoning, learners will gain actionable insights to manage stray current risks throughout the asset lifecycle. Whether you are designing a new metro system or upgrading an existing network, this course equips you with the tools to protect infrastructure and ensure long-term reliability.
