AUTOMATIC PHASE CHANGER

AUTOMATIC PHASE CHANGER
Automation plays a predominant role in the modern scientific world. Automatic phase changer finds application in small offices, residences where single phase equipments are used during phase failure, this unit automatically take the available phase lines and distribute to the non-available phase lines.The circuit is built around a transformer, comparator, transistor &relay. Three identical sets of the circuit, one for each of three phases are used .The power supply provided to the transformers is stepped down which is rectified by the diodes and filtered by a capacitor to produce the operating voltage for OP-AMP. Depending upon the voltage at the output of IC the relay gets energized or de-energized and with this phase can be choosed. Using Automatic phase changer we can operate all our equipment even when the voltage in any of the phase exceeds the rating of the equipment.
