Characteristics:

 

1. The test items cover all relevant parameter detection of circuit breaker mechanical characteristics
2. A new test method for evaluating the wear status of arc extinguishing contacts of circuit breakers: The arc extinguishing contact analysis module allows users to automatically evaluate the degree of wear of arc extinguishing contacts inside the circuit breaker without disassembling the circuit breaker.
3. A new vibration fingerprint test is added to evaluate the status of the circuit breaker from a new perspective: The vibration fingerprint test results contain more abundant circuit breaker operation information, and for circuit breakers with potential fault risks or faults, the fault location can be quickly located.
4. The instrument has a built-in contact resistance tester function to reduce repeated investment
5. Envelope drawing and matching functions to complete the automatic evaluation of the reference mechanical stroke of the circuit breaker
6. Super data management and convenient report making functions make the test process simpler
7. The GDGK-307 circuit breaker analyzer can simultaneously measure the unidirectional parameters of multi-level 4-pole circuit breakers
8. The vibration test does not require changing the original line connection, and users can complete the mechanical characteristics detection of the circuit breaker with power
9. 12.1-inch touch screen control and data input
