C. Becker et al., PROPOSED CHAPTER-9 FOR PREDICTING VOLTAGE SAGS (DIPS) IN REVISION TO IEEE STD-493, THE GOLD-BOOK, IEEE transactions on industry applications, 30(3), 1994, pp. 805-821
Voltage sags, also known as dips, are important to industrial reliabil
ity. Modern process controls are often sensitive to voltage sags. The
combination of voltage sags and sensitive equipment may cause signific
ant production outages. Less sensitive equipment may be available, but
the designer must know sag characteristics of the electric system to
make the best choices between reliability and equipment cost. This pap
er shows how to predict voltage sag performance of electric supply sys
tems by combining a new analysis method with reliability data. The ana
lysis method is proposed for a new chapter in the next revision of IEE
E Std 493.
