Transients are a nuisance for power system designers that can hamper performance and in the worst case cause damage to equipment. A new book, Power System Transients: Theory and Applications, is ...

Electric utility engineers designing new transmission and distribution (T&D) systems and evaluating existing systems have relied on sophisticated software programs that can simulate transients. Now ...

Using the fast dynamic load described in this Design Idea to test the transient response of a power system can reveal many critical operating characteristics. The voltage deviation resulting from a ...

The programmable logic controller (PLC) is an important component in most modern automation and process control systems today. It's also susceptible to lightning-induced transients. To verify the ...

The rate of transient occurrences varies with every power system. Recent studies show that surges of 1kV or less are common — whereas 3kV surges are rare. Protecting against more frequent (internally ...
