A voltage sag is a momentary (i.e., 0.5-30 cycles) decrease in the rms voltage magnitude, usually caused by a remote fault somewhere on the power system. This paper describes the causes of voltage sags in industrial plants, their impacts 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, and motor contractors, is analyzed. Available methods of power conditioning for this sensitive equipment are also described.
