Description

Power Supply System for Railway Signalling ApplicationsIn modern railway networks, a reliable and uninterrupted power supply is the backbone of safe and efficient train operations. Signalling systems — whether traditional relay-based or advanced electronic interlocking — depend on precisely engineered electrical power arrangements to function without failure. This course is designed to provide a comprehensive understanding of the design, operation, maintenance, and troubleshooting of power supply systems specifically tailored for railway signalling applications.Through a structured and practical approach, you will explore:· Secondary Cells & Batteries — including lead-acid, low-maintenance, and VRLA technologies, their charging/discharging characteristics, efficiency, maintenance practices, and lifespan.· Integrated Power Supply (IPS) Systems — components, working principles, SMPS-based designs, protection features, and problem-solving strategies.· Power Supply Arrangements — sources, auxiliary transformers, changeover systems, load distribution, and maintenance responsibilities.· Load Calculations — accurate methods to calculate DC, AC, and IPS loads for various signalling installations.· Protection Systems — earthing, lightning and surge protection, transient suppression, and safe bonding practices.· Solar Applications — harnessing renewable energy for signalling power requirements.· Testing & Commissioning Procedures — including pre-commissioning checklists, performance monitoring, and preventive maintenance routines.By the end of this course, you will be equipped with the knowledge to:· Understand the complete power architecture for signalling installations.· Select, operate, and maintain power equipment as per railway standards.· Identify and resolve common faults to ensure uninterrupted signalling operation.· Apply best practices for safety, efficiency, and long-term reliability.Whether you are a railway signalling engineer, maintenance supervisor, trainee technician, or an enthusiast seeking deep technical insight, this course provides a solid foundation and practical skills for managing railway power supply systems.
