The circuit breaker tester is used to check the operation and condition of the circuit breaker in the power system; for this, the circuit breaker tester applies different signals, which are used to test the equipment under a series of system conditions or operation types. At the same time, the circuit breaker The tester must have the ability to capture and measure in order to be able to evaluate its condition and verify its proper and expected performance; the circuit breaker tester is also a powerful tool for solving faulty circuit breakers
The circuit breaker tester must provide accurate and repeatable results so that it can be compared with previous tests and predict the circuit breaker before it fails. Because the circuit breaker does not work for a short time, the circuit breaker tester must provide Short setup work and connection time, as well as small test complexity. Therefore, a circuit breaker tester must also be designed to save test time and provide a unique combination of functions that effectively optimizes results and methods.
The circuit breaker tester can be used exclusively for medium/high voltage circuit breakers, and can also be used for low voltage circuit breakers. But the multi-function circuit breaker tester can be used for both types at the same time, such as high current injection systems and micro-ohmmeters.
Choose a circuit breaker tester suitable for different applications
In the factory, during commissioning and regular maintenance, the different opening and closing operations of the circuit breaker are tested regularly; when analyzing the trip time, synchronization and movement parameters of the medium voltage/high voltage circuit breaker, in addition to the timing, the synchronization of the electrodes, and the status of the coil, In addition to mechanical motion analysis and the status of the DC battery, the circuit breaker tester is equipped with a rechargeable battery, a built-in printer, an easy-to-use touch screen and graphical results.
