Abstract

ABSTRACT
Reliable and uninterruptible power supply is crucial for mission-critical loads to function efficiently and optimally. However, in most developing countries, electric power supply is characterized by regular failures and when available, it is largely unreliable as the standard three phase power supply is most of the time unbalanced and the quality degraded by fluctuations. This project work involved the design and development of automatic three-phase power supply selector to guarantee uninterruptible and reliable power supply to critical infrastructure. The performance of the automated system was tested and the results showed that whenever there was voltage input or any combination of inputs from the three power phases that served as reference inputs to the control system a voltage output is automatically produced to ensure reliable supply to mission critical loads.
