GB/T 4473-2018
ActiveSynthetic 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, which simulate the electrical stresses of short-circuit interruptions using a combination of current and voltage sources. It is applied in the design verification and type testing of circuit-breakers rated above 1 kV, primarily within the electrical power industry, to ensure their performance under fault conditions without requiring a full-power test facility.
