This is to certify that the research work, "design and construction of an automatic changeover switch" by , Reg. By Dr.

Power failure or outage in general does not promote development to 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. This paper presents the design and construction of an automatic power changeover switch that switches power supply from public supply to generator once there is public power supply outage and it does this automatically. This is achieved by the use of integrated circuits that have timing abilities and relays to effect switching. Keywords: Switching, relay, generator, motor, public power supply, transistor.

It is designed in several blocks all combined to from one functional unit. The output of the BCD — Decimal decoder is used to select the phase in priority through a transistor driver stage and electromagnetic relay that activates contactors. The least prioritized phase is the Gen set which contains a circuitry that automatically starts and stops the Gen set. The system is realized with TTL chips market. LEDs and AC panel lamps are used to indicate the status of the system while a manual switch is used to demonstrate the mode of operation of the system. Approval page ii. Chapter one.

Power failure or outage in general hinders development of public and private sectors in a country as most industrial and commercial processes are dependent on electrical power. This limit the development of industries. Also there are processes that require constant and steady power supply; that is, cannot be interrupted because of their importance. For instance the control tower in an airport, internet banking operation telecommunication base stations and lots more. This paper presents the design and construction of an automatic power changeover switch that switches power supply from public power supply to generator once there is public power supply outage and it does this automatically. The methods employed in designing the automatic change over switch involve the use of electromechanical type relays, contactors, voltage monitoring relays and delay timer relays as main components of the system. The output of the power supply unit which powers the relays was tested by making the relays to change over immediately the power varies with a generator and public supply source.
