AI-Powered supplier vetting

SummaryThe supplier appears to be a sample-customization manufacturer with identified production equipment and a stated annual productivity figure of 5,000 sets. It holds an ISO9001:2015 certificate and reports conducting regular fire drills, but no additional certification detail is provided. The supplier lacks stated 3D software design, ODM, SDK, popular-brand OEM, overseas agent, overseas warehouse, overseas showroom, and in-stock service capabilities. Financial credibility cannot be confirmed because the supplied financial indicators are all reported as zero. Quality control appears limited to one inspector, with finished products checked by packing staff. Customer cases and documented service procedures are not sufficiently evidenced.

Supplier typeThe supplier explicitly states that it is not a professional technical supplier and provides no 3D software design, ODM, SDK, or popular-brand OEM services. Its stated design approach is customization from samples, while production equipment and a 5,000-set productivity figure indicate a manufacturing orientation.

CertificationsThe supplier reports holding an ISO9001:2015 certificate for management systems. Product compliance certification is listed only as “Others,” without a specific standard or certificate being identified, so certification coverage beyond ISO9001 cannot be confirmed.

After-Sales capabilityThe supplier reports no in-stock service, overseas warehouse, overseas showroom, overseas agent, or overseas branch capability, and has not participated in offline trade shows. It provides quotation and payment terms and lists some supplier names, but no clear after-sales service system or documented procedures is shown.

R&D capabilityThe supplier reports no new products during the past year, no professional technical R&D capability, no 3D software design, no ODM service, and no available SDK. These explicit limitations indicate weak evidence of independent innovation capability.

Customization capabilityCustomization from samples is explicitly listed as both an R&D-related design service and a general design capability. This directly supports the supplier’s ability to perform sample-based customization, although no broader engineering or software-design capability is evidenced.

Product Q&A

Q:What is the main function of a three-phase relay protection tester?

It is a specialized device designed to simulate various electrical fault conditions, verify the accuracy and reliability of protection relays, and ensure they can trip or operate correctly when electrical system faults occur.

Q:Can the tester be used for both low-voltage and high-voltage relay testing?

Most three-phase relay protection testers are compatible with low-voltage and medium-voltage relays directly; for high-voltage relay testing, they usually need to cooperate with matching voltage transformers (VTs) or current transformers (CTs) to achieve safe and accurate testing.

Q:What key parameters should be checked before starting a relay test with the tester?

You need to confirm the input voltage of the tester matches the power supply, set the correct test current, voltage, phase angle and frequency according to the relay's rated parameters, and ensure the wiring between the tester and the relay is correct and firm.

Q:How to solve the problem that the tester fails to communicate with the connected PC software?

First, check if the communication cable (such as USB or Ethernet cable) is properly connected and undamaged; then confirm the communication port settings on both the tester and the software are consistent; if necessary, restart both the tester and the PC to re-establish the connection.

Q:Is it necessary to calibrate the three-phase relay protection tester regularly?

Yes, regular calibration is essential. It is recommended to calibrate the tester at least once a year or in accordance with relevant industry standards to maintain the accuracy of its output current, voltage and other parameters, ensuring reliable test results.
