    This Project can be used with the three phase Induction motors. The circuit will take the full control of the motor and it will protect the motor from several faults such us over voltage and under voltage and the circuit will switch on the motor under safety conditions.
    The circuit was fully controlled by the microcontroller and the microcontroller will continuously monitors the voltages of the three phase and if the voltage goes abnormal then it will switch off the motor until they are normal. All the conditions are displayed it over the LCD display. In our project we are using the popular 8 bit microcontroller AT89S52. It is a 40 pin microcontroller.

    The Low/high Voltage ratings can set by using the Variable resistors(Preset) in the circuit.

    sir,
    What should be the maximum voltage at which the circuit works and what is the minimum time that voltage should exist for the circuit to start the operation.
