Guidelines for uniform measurement and reporting of sound produced by AC power circuit breakers are established. The methods are intended for measuring the sound produced by outdoor circuit breakers in…
As an aid in testing circuit breakers under conditions of switching capacitive currents synthetic test circuits may be used. The design of the circuit should simulate the stress of actual…
Distributed multi-computer master stations and distributed remote terminal units (RTUs) are introduced. Submaster RTUs used in an automated distribution system with downstream feeder RTUs is defined. Local area networks with…
This standard applies to, and provides the basis for the definition, specification, performance analysis, and application of systems used for supervisory control, data acquisition or automatic control, or both, in…
Acceptable performance criteria for solid-state electricity meters are established. Detachable socket, type S, and bottom-connected, type A, as well as any other arrangement agreed upon between the manufacturer and the…
A rating structure for AC high-voltage circuit breakers rated on a symmetrical current basis is established. The rating structure applies to indoor and outdoor types of AC high-voltage circuit breakers…
This standard covers the rating structure for all high-voltage circuit breakers, which include all voltage ratings above 1000 V ac and comprise both indoor and outdoor types having the preferred…
