COURSE OBJECTIVES

The training aims to equip participants with the technical knowledge and practical skills required for the safe and efficient operation of 220 kV/27.5 kV Traction Power Substations (TPS), covering electrical safety, Permit to Work (PTW), switching, isolation and earthing procedures, SCADA monitoring and control, traction power feeding and sectorization, equipment condition monitoring, fault diagnosis and emergency response, while strengthening operational coordination and decision-making to enhance personnel safety, equipment reliability and continuity of railway services. The training will be delivered in two batches, each lasting five (5) days: Batch 1: 16–20 November 2026 and Batch 2: 7–11 December 2026, with daily sessions running from 9:00 AM to 4:00 PM.
