This standard establishes basic requirements for the control schemes of electrically controlled ac highvoltage circuit breakers rated above 1000 V. This standard is applicable to any type of power-operated mechanism and for both ac and dc control power. Only the basic control elements of the circuit breaker@ including reclosing where required@ are included in this standard. This standard does not include devices or circuits for protective relaying@ special interlocking@ etc.@ since these are dependent upon the specific application of a particular circuit breaker. Purpose The purpose of this standard is to establish basic requirements for ac high-voltage power circuit breaker control schemes so that users and manufacturers can affect engineering and production economies by reducing the multiplicity of special control schemes that are specified in the absence of standards.
