Design And Implementation Of Android Base Automatic Phase Selector And Overload Protector Using Gsm

ABSTRACT The project is designed to automatically supply continuous power to a load through one of the three sources of supply that are: solar, mains and generator or to combine the sources to supply the load all together at the same time. The three socket outlets represent the three sources. The sockets outlets are connected to three step down transformers which reduce the input 230V or 240V to 12Vac. These 12Vac are rectified and regulated to 5Vdc which act as an input to the microcontroller. Once the microcontroller recognize the present of a given source, a relay module is switch to an ON …
