97-10: Mechanical Damage Caused by EMF Generated from Fast Bus Reclosure Corrosion

97-10: Mechanical Damage Caused by EMF Generated from Fast Bus Reclosure CorrosionEnergy conservation considerations have led to the increasing use of two speed motors and variable frequency drives for mechanical draft cooling towers. While this practice has resulted in improved efficiency, its proper application has several hidden pitfalls that must be considered when specifying the motor control and mechanical components in the system.
