ABSTRACT
An automatic change over display
with micro controller is designed to switch electric current from main power
source to an alternative power supply (generator) without human intervention.
The purpose of this project is to maintain constant supply to the main circuit
that is being supplied by making-up for the time lapse or delay that usually
accompanies the manual switching from one source to another. The major
component in this construction is the microcontrollcr which is a small computer
on a single integrated circuit containing processor core, memory and
programmable input/output peripherals. The microcontroller turns ON and OFF the
generator set, changes output to the load from commercial power supply to
generator output or from generator output through a 12V relay. If there is no
power supply present the circuit automatically starts kicking the generator
set, to try the generator three times. If the generator does not start after
three attempts, then the circuit will assume there is a fault on the generator,
which will require the user to restart the generator set. The circuit displays
an error messages if there is a fault on the generator, either from starting
the generator set, and sudden stopping of the generator set. The result for
this construction is to successfully switch electricity from the main power
supply to the alternative power supply. In conclusion, the construction helped
the author to know about automations.
