Smart socket for eliminating phantom power

Abstract

In our modern age, many people have multiple devices such as laptops, tablets, and smartphones, all of which needs to be frequently charged to keep us connected. This has led to multiple chargers being left at home and at the office, often plugged into the wall with the cord conveniently waiting to charge your phone for next time. Chargers continually draw power from a wall socket, even when your device is not attached, and while this amount could be as little say 0.25 Watts of energy, imagine that compounded over 4-5 devices for a year will lead to 2190 Wh per year for a single user. According to Telecom authority of India, Tamil Nadu has 71.81 million smartphone subscribers [1] so this phantom power consumption must be accountable. Additionally standby loads are found to be next phantom power consumers which consumes power when appliance switched off or not performing its primary functions. This proposed work will eliminate wastage of power at standby and prevent overcharging of mobile phones furthermore turn off scheduler is incorporated for planned operated loads.
