Design and Simulation of a Versatile Three-Phase Automatic Changeover Switch

The importance of a changeover/ transfer switch cannot be understated. When using a generator, this switch attempts to provide a smooth transition. A transfer switch is created in this project for a college in Ghana, to enable it to switch electricity from the utility to a different source. Previously, a manual switch was used, which was activated by physically moving a lever. However, with this newly improved switch, if it deems the power to be out (due to heavy rains or an electrical accident), it will instantly and safely change-over to the generator or solar power. Ultimately providing electricity to critical functions (set precedingly). The final circuit was carefully designed and divided into two halves, for better explanation. The starter circuits were specially designed to simulate how the auto switch-over will be powered (either through a single or three phase supply). The end circuits were utilized to show how the auto switchover gives users feedback. The overall outcome of the project is a combination of the start, and end circuit. This resulted in the adaptable auto-transfer switch. The project has an immediate impact on three Sustainable Development Goals (SDGs): 7, 9, and 11. This is due to the fact that it is an innovation that promotes clean energy, while also contributing to smart cities.
