Abstract :
The probability of maintaining process continuity during voltage dips can be greatly enhanced by arranging the motor control circuits so that the essential motors remain connected to the line during a voltage dip. It is equally important to remove the non-essential load from the line to minimize the system disturbance while re-accelerating the process. However keeping the motor connected to the line during a voltage outage and subsequent reclosure can result in motor damage. Therefore, where reclosing can occur, it is necessary to consider the preventive measures to minimize the probability of motor damage while maintaining maximum reliability of service.
