Power Quality is an important factor in maintaining production output in every industrial facility. In addition to loss of production due to equipment shutdown, product quality may also be affected when equipment continues to operate under poor power quality conditions. It is therefore not sufficient to merely keep equipment operating through power disturbances, but rather, it may also be necessary for some processes to engage in an orderly shutdown when a disturbance occurs. In addition to power quality problems, other important factors in maintaining industrial production is both the avoidance and correction An adjustable speed drive that is not functioning properly is often not in need of repair. It may be found to have some problem with the incoming power source, the signal and power wiring technique, the programming, or perhaps the drive has not been specified properly for Thus, if a drive is turning the motor and the service personnel can not effect a repair, the problem may not be a failed drive but, System considerations that affect the performance of a drive are indeed often overlooked. Power Quality and Drives presents information needed to help resolve the failed application problem. Other power quality related topics addressed are: Starting currents and torques of effects of short circuit capacity on drive application, transformer sizing, selection of current limiting fuses, and variable speed drive Please return to the Power Quality and Drives LLC home page often for the latest topics. Rotary power supplies for use with variable frequency drives are available that will allow ride-through of the drive for up to five Enhanced motor protection will not only lower motor rewinding and repair costs but will also lower over-all down time and yield an
