Applies to all types of electrically controlled ac high-voltage circuit breakers rated above 1000 V. Establishes basic requirements for ac high-voltage power circuit breaker control schemes so that users and manufacturers can effect engineering and production economies by reducing the multiplicity of special control schemes that are specified in the absence of standards
