Thesis Abstract
This is the design and construction of an Automatic Phase Selector. In the construction work, LM324 integrated circuit (comparator) and 2N2222 transistors were used as active components alongside other passive components. The circuit components were mounted on a Vero board. Result shows that, when the three phase A.C inputs Red phase (P1), yellow phase (P2) and blue phase (P3) from public utility supply was fed to the system, the system compared the inputs with regards to phase imbalances, and the input with the highest voltage appears across the output. It also changes over from one phase to anothe4r immediately the circuit senses further phase imbalance.
Keywords Relay, Switch, Comparator, Phase Selector, Automatic.
