2020年10月26日 · ANSI C84.1-2020 provides a better understanding of voltages associated with power systems and utilization equipment by establishing nominal voltage ratings and operating tolerances for 60 Hz electric power systems above 100 volts. This standard also includes voltage ratings up to and including 1200 kV maximum system voltage.

The national standard for utility voltage tolerance in North America is ANSI C84.1. This standard establishes nominal voltage ratings and operating tolerances for 60Hz electric power systems above 100 volts. This standard includes preferred voltage ratings up to and including 1,200kV maximum system voltage.
