The circuit breaker tester is used to check the operation and condition of circuit breakers in the power system. To this end, the circuit breaker tester imposes different signals that are used to test the device under a range of system conditions or types of operation, and the circuit breaker tester must have the ability to capture and measure in order to be able to assess its condition and verify its appropriate and expected performance; Circuit breaker tester is also a powerful tool for solving faulty circuit breakers.

Circuit breaker tester must provide accurate and repeatable results, so that you can compared with previous tests and to predict before the circuit breaker failure occurs, as a result of the circuit breaker is not work time is short, so the circuit breaker tester must provide the shortest work Settings and the connection time, as well as the minimum testing complexity. Therefore, circuit breaker testers must also be designed to save test time and provide a unique combination of functions that effectively optimize results and methods.

Circuit breaker testers can be used specifically for medium/high voltage circuit breakers or low voltage circuit breakers. But multifunctional circuit breaker testers can be used in both types, such as high-current injection systems and microohmmeters.
