Phase selector is a mechanism used in alternating
or switching between power phases with respect to the availability
of power on any of the phases. Over the decades, there has been
frequent phase failure in the power phases resulting to manual
switching of the fuse from one phase to the other. However, this
paper focuses on the design of a phase selector using automatic
switching mechanism. This during its operation, transfers the
consumer’s loads to the available power source in the case of
power failure in the power supply from the national grid and
automatically detects when power is restored to the failed phase
and returns the loads to this source. In the course of this design,
several tests were carried out such as the continuity test of
contactor and relay coils to ascertain low resistance, continuity
test on the contacts of the materials used to ensure free flow of
current, conductivity of the wires and the whole system was also
simulated using the Proteus electronics software.
