In working with heavy AC and DC appliance problems that arise are common nowadays. Here a new protection method is implemented which is low cost and reliable. The fault that occurs normally in the appliances are over voltage/current fault or under voltage fault or short-circuit problems including system blackout or some other problems regarding frequency disturbances etc. Failure of insulation or occurrence of any of the above-mentioned faults will reduce the life of electrical appliances and can cause enormous economic damages and even sometimes life risk problems. Here we are super excited to implement a protection scheme which is of societal use which will reduce the life and asset damages. This protection scheme is implemented by using ATmega2560 microcontroller.
