A REVIEW PAPER ON DESIGN OF COOLING SYSTEM FOR ELECTRICAL TRANSFORMERS, CIRCUIT BREAKERS USED IN TRANSMISSION STATION

Transformer is a device that transfers electric energy from one alternating-current circuit to one or more circuits, either increasing (stepping up) or reducing (stepping down) the voltage. Transformer plays a key role in the power transmission, during this power transmission heat is generated. Cooling of a transformer is the dissipation of heat developed in the transformer to the surroundings. The losses occurring in the transformer are converted into heat which increases the temperature of the windings and the core. In order to dissipate the heat generated cooling should be used. A circuit breaker is an electrical switch that turns off automatically during an overload or short circuit. These switches are important because they protect your electrical components from overheating and breaking. By using different cooling methods we design an cooling system for the transformer and circuit breaker by using Revit software. By using this method, the temperature of transformer and circuit breakers can be reduced in short time. According to generally adopted estimate states that if a transformer’s maximum operating temperature is reduced by 6°C-10°C. The main purpose of the experiment is to improve the cooling system of transformer, to increase the life expectancy of transformer.
