A Review of Frequently Unrecognized Considerations in the Design and Operation of Industrial Power Systems

This paper reviews system design problems that frequently are not recognized early enough in the design of an industrial power distribution system to avoid awkward, troublesome, and sometimes costly changes. Most of the problems result from unusual or infrequent circumstances or unforeseen situations. Many are recurrent, however, indicating a lack of sufficient coverage in the literature. These problems have been selected from the authors´ experiences as manufacturers of switchgear, in the interpretation of specifications for the functional requirements of switchgear for many industrial power systems.
