    Three Phase Changer With Display


    Abstract

    This project is developed for the users to change the phase when one or two phase not available. The main part of the circuit is a microcontroller PIC16F73. The three phases are directly connected with three step down transformers and the output of the three transformers are regulated to 5V DC. The three five volts are given as input to the ADC of the microcontroller. The output of the microcontroller is connected with a relay through driver. The three phase motor is connected with the relay. The display indicates the phases which are currently activated. The microcontroller program is written in such a way that when three inputs are present, the microcontroller sends signal to the driver section and there by operates the relay. If any one or two of the inputs are absent, the microcontroller will not send signal through the output port and thereby it automatically trips the available phase through the particular relay. The microcontroller program is written in assembly language.
