The scope for the future enhancement of the circuit is also shown in the block diagram. If an amplifier connected to the motor or various other equipment at the power grid is connected to the microcontroller circuit and suitable programming is done then along with the fault detection controlling of power grid can also be done by the use of GSM technology.
