Scope

This standard applies to high-voltage AC circuit breakers within the scope of GB/T 1984-2014. Within the test methods specified in GB/T 1984-2014 from 6.102 to 6.111, it provides general rules for testing the closing and breaking capacity of high-voltage AC circuit breakers using a synthetic method. The methods and techniques described in this standard are universal. The purpose of this standard is to determine the criteria for synthetic testing and to make a proper evaluation of the test results. These criteria will determine the effectiveness of the test methods without increasing the constraints due to the updating of the test circuit.
