Although, in developing countries, the electric power generated to meet the demands of the growing consumers of electricity is insufficient, hence power instability and outage. Power instability or outage, in general, does not promote development in the public and private sector. The investors do not feel secure to come into a country with constant or frequent power failure. These limit the development of industries. In addition, there are processes that cannot be interrupted because of their importance for instance, surgery operation in hospitals, transfer of money between banks and lots more. Power instability and outage in developing countries (Nigeria) creates a need for alternative sources of power to backup the mains supply. Automatic changeover switches find a wide application scope wherever the reliability of electrical supply from the utilities is low and it is used in lighting/motor circuits wherever continuity of supply is necessary, for switching to an alternative source from the main supply and vice versa. This project is a design of an automatic changeover switch. This means that when there is any mains failure, the automatic changeover switch will change to an alternative power supply (Generator), and back to the main supply when it is restored. The purpose of this project is to maintain a constant supply to the main circuit that is being supplied by making-up for the time-lapse or delay that usually accompanies the manual switching from one source to another. The design comprises of the power connection circuit and control connection circuit. The main components to be used include contactors, relays, and timer....Preview Download Preview +Other Electrical Electronics Engineering project topics and materials you might be interested in»The construction of a 2kva automatic voltage regulator (AVR)»Generation of Constant Power Supply from a DC Source»Design and construction of a digital clock with calendar»Construction of digital AC power controller»A remote controlled AC fan speed regulator using discrete integrated circuit»Remote controlled antenna»The construction of automatic voltage inverter and a battery charger»Design of 2.5kw automatic voltage regulation with seven segment display»Simple sensitive touch alarm»Construction of a car touch intruder alarm»Design and construction of 2KVA inverter»Design and construction of 5kva power inverter»Design and installation of 200 WATT solar power system»Design and construction of an automatic change over switch»Construction of a battery charger
