  • Patent number: 11402457
    Abstract: A system and a method for an integrated test on a primary-secondary pole-mounted breaker. The method includes: establishing an electrical connection between the system and the primary-secondary pole-mounted breaker; establishing a communication connection between the system and the primary-secondary pole-mounted breaker; applying, by the system, a voltage signal and a current signal to the primary-secondary pole-mounted breaker through the electrical connection, to generate a voltage and a current on the primary-secondary pole-mounted breaker; collecting, by the system, signals of the voltage and the current fed back from the primary-secondary pole-mounted breaker through the communication connection; performing, by the system, an integrated accuracy test and an integrated protection test; outputting a test result of the accuracy test and a test result of the integrated protection test to the industrial control machine, to generate the test report.
