What is "System Voltage" defined as?

System voltage is defined as the phase-to-phase voltage value in a three-phase system. This measurement is crucial for understanding and assessing the electrical performance of the system. In a three-phase arrangement, the phase-to-phase voltage represents the voltage measured between any two phases. This is significant because it is the voltage primarily used in the operation of three-phase equipment, which is the standard for most industrial and commercial power systems.

Knowing the phase-to-phase voltage allows linemen and electrical professionals to ensure that the equipment operates within its designed specifications and maintains system reliability. This parameter is essential for proper load calculations, equipment ratings, and electrical safety. It is the standard reference for specifying and rating electrical equipment and components, making it vital in planning and installation processes.

Other choices may refer to relevant voltage aspects, but they do not encapsulate the complete definition of "system voltage" in the context of commonly accepted electrical principles. For instance, voltage to ground pertains primarily to safety aspects and grounding issues, while maximum voltage rating and minimum operating voltage are more about equipment specifications rather than the system voltage itself.
