The automatic transfer switch is helpful transfer the load from various power sources to ensure continuous operation of load. Automatic transfer switch is needed in developing countries where frequent power failure is a major problem. Industries, public and private sector organization and even domestic user cannot handle power outage due to it pushes them in loss in business disturbance in normal official work, hindrance in routine and domestic life. In this system we have highlighted the use of good border in term of switching speeds and smooth evolution. Allowable by means of an automatic connection to a network of other sources of supply in case the main source of power supply distress. The automatic transfer switch which is a switchgear control system, provides a functional system that offers an automatic switching of power supply between a primary source and secondary source is generator. The method laboring in designing the automatic transfer switch include the use of electromechanical relay, contactor, voltage monitoring relay and delay timer relays as main component of the system.
