Is there a mobile app out there that can automatically render a percentage imbalance of voltage when you input the 3 voltages in a 3-phase system? Please see the example:
A small imbalance in the input voltage can result in a considerable amount of heat being generated in the motor windings. An imbalance of only 5%, for example, can increase the winding temperature as much as 50% above the safe level.
