DESIGN AND CONSTRUCTION OF AUTOMATIC PHASE SELECTOR

DESIGN AND CONSTRUCTION OF AUTOMATIC PHASE SELECTOR

CHAPTER ONE
INTRODUCTION
As the growing population of human race widens the gulf between energy supply
and energy demand, the imbalance in energy availability sent researchers into
excavating for a way of settling this age long squabble. A lasting solution is vested
on alternative use of the renewable energy source, a project that is yet to be
widely applied. Hence, the continuation of the unsettled yearns for sufficient
power. Consequently, the power lines are frequently over loaded resulting to a
trip of power by the action of switch gears or by the load shading process
undertaken by the distribution authorities.
Since it is crystal clear that some institutions such as health related institutions
and some other delicate systems should not be allowed to suffer equally with
their counterparts, Automatic Phase Selector is used to sustain energy
consumption in the time of phase trip. The design of this circuit involves the use
of automatic switches but the details of design varies from place to place, time to
time and also depends on the type of load involved.
This project involves the use of transistor driven relays to affect the change of
phase whenever the voltage condition becomes intolerable in the previous phase
connected.
