Abstract: The process of switching the electrical load, that is been powered by two alternative sources (utility and generator), from one source to the other forms part of a change-over process. This process which further includes the monitoring of the supply from utility and the starting/ stopping of the generator to certain extent could be rigorous. To ease such difficulty, the design of an automatic change-over switch has been realized and tested as presented in this paper. Success was recorded as the above processes were automated. This was achieved with the combination of discrete electrical and electronics components which includes PIC16F877A, relays, transistors, diodes, resistors and a liquid crystal display (LCD) for displaying the system status.
Keywords: electrical load, utility, generator, electrical and electronics components.
