• The integrated vibration test function of Circuit Breaker Analyzer provides a new means of detection circuit breaker mechanical characteristics for users, compared to traditional time measurement and speed measurement, the vibration fingerprint detection is easier and more efficient.
• The vibration fingerprint test results contain richer information of circuit breaker operation, for potential risk of failure or faulty breakers, it can locate the fault position quickly.
• The vibration tests do not need to change the original line connection, so the users can complete the charged detection of mechanical characteristics of circuit breaker.
• Arcing contact analysis module allows users to automatically assess the degree of loss of inside Arc suppression contact of circuit breaker without disassembly.
• Users can use Circuit Breaker Analyzer to complete the contact resistance tests, do not need to buy contact resistance tester separately.
