Voltage unbalance degrades performance and shortens the life of a three-phase motor. It causes phase current unbalance far out of proportion to the voltage unbalance. Unbalanced currents lead to torque pulsations, increased vibrations and mechanical stresses, increased losses, and motor overheating, which results in a shorter winding insulation life.
Bob gets a call to go to an office building where its water-cooled chiller is not cooling the building.
