The timing test of different opening and closing operations of the circuit breaker is an effective method for testing the circuit breaker. The circuit breaker characteristic tester not only analyzes the trip time, but also analyzes the basic synchronization of each pole in different operations. It defines how to pass different Operational simulation to test the circuit breaker. The simulation can be issued directly from the circuit breaker analyzer, or it can be initiated by an external signal to check the opening or closing time of each pole in single or combined operation, and check the possible existence between the poles. Differences or mismatches in time, which can lead to a serious lack of synchronization.

How to test a circuit breaker with a circuit breaker characteristic tester also depends on the type of possible problem to be confirmed. This leads to checking other functions. For example, possible runout, the correct performance of the resistor before insertion, the condition of the coil, and the mechanical analysis of the contact travel speed and acceleration data using suitable sensors.

Circuit breaker characteristic tester, which includes all the above-mentioned functions required for the evaluation of the status of medium and high voltage circuit breakers; the method of testing circuit breakers must also consider the short time that the circuit breaker does not work, thereby minimizing the complexity of setting up, connection and testing ; All the above factors are considered in the design, and the same contact resistance is measured, which saves a lot of test time; it is also equipped with a rechargeable battery, a built-in printer, an easy-to-use touch screen, and is very small in size and easy to transport.
