Organization: NEMA
Publication Date: 1 January 2020
Status: active
Page Count: 23
scope:

This Standard establishes nominal voltage ratings and operating tolerances for 60 Hz electric power systems above 100 volts. It also makes recommendations to other standardizing groups with respect to voltage ratings for equipment used on power systems and for utilization devices connected to such systems.

This Standard includes preferred voltage ratings up to and including 1200 kV maximum system voltage, as defined in the Standard.

In defining maximum system voltage, voltage transients, and temporary overvoltages caused by abnormal system conditions such as faults, load rejection, and the like are excluded. However, voltage transients and temporary overvoltages may affect equipment operating performance and are considered in equipment application.
