3 Phase Refrigeration Compressor Wiring Diagram
To operate high power equipment and appliances such as electric motors and and high power rated air compressor etc we need three phase power supply instead of single phase power supply. We know that the compressor motor or fridge compressor has split phase induction motor which has two types of winding.
