CBA.307A
About the CBA.307A:

  • Circuit Breaker Analyzer CBA.307 is used for testing, analysing and assessing power system circuit breakers, mechanical characteristics of load switches and isolated switches and other AC high voltage switches, contact resistance, arcing contacts and vibration characteristics etc.

​

  • The functions of Circuit Breaker Analyzer cover all testing items of high voltage circuit breaks.

​

  • Comparing with the traditional circuit breaker tester, this analyser has unique advantages.
