Circuit Breaker Comprehensive Tester

Professional integrated testing device for 10kV high-voltage circuit breakers, integrating multiple single-test functions for the whole process of electrical equipment testing.

Separated HV/LV modules for higher safety, intelligent sequential testing to reduce wiring, storable & analyzable data, easy operation in line with national standards.

Acceptance, preventive testing of electrical equipment and on-site rapid testing of 10kV circuit breakers, suitable for power grids, substations and other scenarios.

With the development of the times, a stable and reliable power supply has become a necessary condition for social progress, making high-voltage circuit breakers, which play a crucial role in control and protection, particularly important. Therefore, the measurement and evaluation of high-voltage circuit breaker performance are indispensable parts of both the acceptance testing and preventative testing of electrical equipment. However, due to objective needs, field testing of high-voltage circuit breakers involves a large number of devices under test and a wide variety of testing items, requiring the carrying of numerous types of testing equipment. Repeated wiring is common during testing, which not only increases the workload of personnel but also seriously affects work efficiency and even poses certain safety hazards.

To address the aforementioned issues, our company developed this comprehensive circuit breaker testing instrument. It integrates various traditional single-type testing devices, combining years of field testing experience with advanced data algorithms to significantly reduce repetitive wiring, optimize the testing process, and improve work efficiency. Furthermore, the separation of high and low voltage testing modules enhances testing safety, improves storage efficiency, and simplifies operation.
