What is Preventing Voltage Unbalance in Motors about?
Voltage unbalance degrades motor performance and lifespan by causing current unbalance, increased vibrations and temperatures, and reduced efficiency. It is defined as a voltage deviation over 1% and commonly results from uneven loads, faults, or an unstable utility supply. Correcting unbalance through monitoring, load distribution, and maintenance can significantly reduce energy costs and motor wear. For a 100hp motor run at 2.5% unbalance, annual energy savings were estimated at 9517kWh and $476 after fix
