- Scope
- This standard specifies the general rules for composite tests of AC high-voltage circuit breakers, test techniques and methods for short-circuit breaking and closing composite tests, basic short-circuit test methods and arcing time difference. This standard applies to circuit breakers within the jurisdiction of GB 1984 "AC High Voltage Circuit Breakers". The test results of the short-circuit breaking and closing tests carried out in compliance with the provisions of this standard are equivalent to the corresponding direct tests. When other electrical appliances need to use the synthetic test method to determine the breaking and closing capabilities, they can refer to this standard for regulations. . This standard involves synthetic test methods and techniques commonly used at present, aiming to establish criteria for synthetic tests and correct evaluation of test results, and the improvement of test circuits is not limited.
