    Automatic transfer switch
    (University of Management and Technology, 2012) Faisal Khursheed; Sabtain Malik, Muhammad; Umair Dar, Muhammad
    An automatic Generator protection system is designed and developed. In this project all parameters of generator protection like over voltage, over current, over load, over temperature are controlled. . If any parameter will change from reference level the controller will observe and sent the instruction to the system keep it at reference level if possible otherwise trip the load and relax the generator. An electrical transfer switch that operates without the need for manual intervention. It is an electrical device that transfers the source of power being used from one power supply to another. Typically this transfer is between the local utility and emergency source of power and back. It maintains constant monitoring of voltage levels on the electrical circuit. It interfaces with a generator and building’s electrical system. It monitors the utility power and signals the generator to start if as the utility power drops out entirely. Backup power is now fed to the main utility panel or an emergency panel via ATS.
