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.

Computer-assisted personal interviewing example of a situation in which CAPI is used as the method of data collection is the British Crime Survey. Characteristics of this interviewing technique are: This form of interview is substantially cheaper when a large number of respondents is required, because: The big difference between a computer-assisted self interview (CASI) and a computer-assisted personal interview (CAPI) is that in the latter an interviewer is present, but not in the former. There are two kinds of computer-assisted self interviewing: a "video-CASI" and an "audio-CASI". Both types of computer-assisted self interviewing might have a big advantage over computer-assisted personal interviewing, because
