This article analyzed the content about three phase full voltage making test in "GB 1984—2014 Highvoltage alternating circuit-breaker"

"GB/T 4473—2008 Synthetic testing of high-voltage alternating circuit-breaker"and "STL guide". According to the analysis

this article compared two test circuits for three phase full voltage making test depending on the simulation of voltage and current waveform during the short-circuit making process in direct test circuit. In the conclusion

this article puts forward a test circuit which is easy to implement and has a better equivalence for three phase full voltage making test. The results show that the circuit is less difficult than the current standard recommended circuit

and the laboratory can choose the test circuit.
