IEEE Recommended Practice for the Design of Industrial and Commercial Power Systems: Voltage Considerations

Abstract

Information concerning system voltage nomenclature and the preferred voltage ratings of distribution apparatus and utilization equipment are contained in this recommended practice. This is essential to proper voltage identification throughout a power distribution system. The dynamic characteristics of the system and the proper principles of voltage control applied so that satisfactory voltages will be supplied to utilization equipment under operating conditions are discussed. An understanding of system voltage nomenclature and the preferred voltage ratings of distribution apparatus and utilization equipment is essential to help ensure proper voltage identification throughout a power distribution system. The dynamic characteristics of the system need to be recognized, and the proper principles of voltage control applied so that satisfactory voltages will be supplied to all utilization equipment under all normal conditions of operation.
