Power factor correction: a guide for the plant engineer
... less than full load. This often occurs in cycle processes—such as those using circular saws, ball mills, conveyors, compressors, grinders, punch presses, and the like—where motors are sized for the heaviest load. Examples of situations where low power factor (from 30% to 50%) occur include a surface ...
