Description
Circuit Breaker Analyzer HYGK-307 is used for testing, analyzing 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 analyzer has unique advantages.
Features
★ 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, so there is no need to buy contact resistance tester separately.
