Substation Equipments

This course provides a practical understanding of the major equipment used in electrical substations and their role in reliable power transmission and distribution. Participants learn about power transformers, circuit breakers, isolators, busbars, current transformers, potential transformers, surge arresters, batteries, and earthing systems. The course explains the basic construction, working principles, ratings, and applications of different substation equipment. It also covers equipment selection, installation, inspection, testing, and commissioning practices. Participants gain knowledge of protection systems and how equipment works together to detect and isolate electrical faults. The course introduces common equipment failures, maintenance requirements, and troubleshooting methods. Safety practices for working around high-voltage substation equipment are also discussed. Practical maintenance and condition-monitoring techniques are included to improve equipment reliability and service life. The course is suitable for engineers, technicians, electrical maintenance professionals, and personnel involved in power transmission and distribution.
