Voltage sags in industrial systems
Conference Record. Industrial and Commercial Power Systems Technical Conference 1991, 1993A description is given of the causes of voltage sags in industrial plants, their impact on equipment operation, and possible solutions. The definition proposed focuses on system faults as the major cause of voltage sags. The sensitivity of different types of industrial equipment, including adjustable speed drive controls, programmable logic controllers,

Voltage sag compensation with energy optimized dynamic voltage restorer
IEEE Transactions on Power Delivery, 2002The compensation capability of a dynamic voltage restorer (DVR) depends primarily on the maximum voltage injection ability and the amount of stored energy available within the restorer. A new phase advance compensation (PAC) strategy for the DVR is proposed in order to enhance the voltage restoration property of the device.

Before and during voltage sags
IEEE Industry Applications Magazine, 2005The relationship between the voltages and the tripping level for line-operated synchronous machines is discussed. Voltage sags may cause tripping and large torque peaks in electrical machines. Tripping is caused by undervoltage protection or overcurrent protection.
