Power systems CAD Power systems CAD In electrical power engineering, power systems CAD is computer-aided design (CAD) software that is used to design and simulate electrical power systems in commercial and industrial buildings. Electrical power systems CAD tools are used by electrical power systems engineers. In the United States alone, power systems are a $100 billion industry. Power systems CAD tools increase the productivity, efficiency, and effectiveness of electrical systems designers by providing a design foundation that allows power systems to be created quickly and by enabling design engineers to test the safety and integrity of their design concepts.

Acronym was formed from the Greek words , ', "topmost, extreme" and , ', "name.") For example, the army offense of being "absent without official leave" was abbreviated to "A.W.O.L." in reports, but when pronounced as a word ("awol"), it became an acronym.
