GB/T 4473-2008
AbolishedSynthetic testing of high-voltage alternating current circuit-breakers
高压交流断路器的合成试验
Application Summary AI generated
This standard specifies the methods and procedures for synthetic testing of high-voltage alternating current circuit-breakers, where the test current and voltage are supplied from separate sources to simulate real fault conditions. It is applied in electrical engineering for type testing of circuit-breakers rated above 1 kV, ensuring their ability to interrupt fault currents under controlled laboratory conditions. The standard is used by manufacturers, testing laboratories, and utilities to verify performance without requiring a full-power test circuit.
