CHAPTER ONE - [ Total Page(s): 1 ]Raw power instability in developing countries creates a need for automation of electrical power generation or alternative sources of power to back up the utility supply. This automation is required as the rate of power outage becomes predominantly high. Most industrial and commercial processes are dependent on power supply and if it processes of change-over are manual, serious time is not only wasted but also creates devices or machine damages from human error during the change-over connections,which could bring massive losses.The starting of the generator is done by a relay whi ...
