This course will cover the fundamentals of heat loss calculations, factors affecting heat loss in substations, and methods to minimize heat loss and improve overall performance. Heat loss and temperature rise in electrical substations directly affect equipment life, reliability, and safety. Incorrect heat loss calculations can lead to overheating, insulation failure, forced outages, and reduced equipment lifespan. This course teaches you how to calculate heat losses in electrical substations and use those results to design proper ventilation, cooling, and safe layouts.
