Test method
Due to the relatively slow voltage and current waveforms of the surge test, the configuration of the test room is relatively simple. For the tests on the power line, they are all completed through a coupling/decoupling network
The following points should be noted during the test:
Before the test, it is necessary to add protective measures according to the manufacturer's requirements.
The test rate should be set once per minute, and should not be too fast to provide a performance recovery process for the protective device. In fact, the phenomenon of lightning strikes in nature and the switching of large switches in switchyards cannot have a very high repetition rateThe test is generally conducted 5 times for both positive and negative polarity
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
