However, the methods and equipment employed to effect power supply changeover remain fraught with challenges ranging from inefficiency to cost. Most industries still employ the manual method of power supply changeover, which is beset by a myriad of setbacks including: time wastage, strenuous operation, susceptibility to fire outbreak and high maintenance frequency. This paper presents a Microcontroller-Based Automatic Transfer Switching System (MBATSS), which eliminates the challenges of a manual changeover system. A voltage sensing circuit, a Hall Effect current sensor, relays, LEDs and an LCD were all coordinated using a PIC16F877A microcontroller. A system flow chart was developed for the firmware and the microcontroller programmed using GCG BASIC programming software. The simulation of the designed circuitry was conducted using proteus design suit software. The simulation results vindicated the method used, thus, confirming the workability of the proposed design. Duration analysis yielded excellent results, as approximately 20 seconds elapses during the entire process of power supply changeover. The timely restoration of power and ease of operation are some of the advantages attributable to the design.
