Baijian Testing is mainly engaged in textile, insulation, cosmetics, food, hardware industry related product testing, as well as providing product certification services, but also in the broadening of the scope of the testing industry, the laboratory issued a report can be stamped CNAS/CMA/CAL qualification seal, the report is true and effective.
Display style: electronic
version of the testing cycle: 3-15 working days (expedited available)
Report qualification: CNAS, CMA, CAL, etc
All electronic devices are used in the high potential side sensing heads of electronic current transformers. On the high potential side, a hollow coil (Rogowski coil) is used to convert the bus current into a voltage signal. The voltage signal is an analog quantity, which is converted into a digital signal through A/D conversion. The digital signal is converted into an optical signal using an electro-optic conversion (LED) circuit, and then transmitted to the low potential side through an insulated optical fiber. On the low potential side, the optical signal is converted into a digital electrical signal by a photoelectric converter (PIN) for use in relay protection and energy metering. In situations where analog quantities are required, digital to analog (D/A) circuits can be used to convert digital quantities into analog quantities. It uses a hollow coil (Rogowski coil) to measure current, without iron core, and has characteristics such as high measurement accuracy, good linearity, large dynamic current range, and wide frequency measurement characteristics. Its data signal is transmitted through optical fiber, with high insulation performance, thus achieving complete isolation of primary and secondary equipment, greatly improving the safety and reliability of the system operation, It can meet the needs of digitization, intelligence, and networking of power system meters and relay protection
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 problems100% inspection and testing process:
