AI-Powered supplier vetting

SummaryHV Hipot Electric Co., Ltd. is a China-based factory and limited company in Wuhan, Hubei, established in 2006 according to the company profile, while another description states operations began in 2003. It manufactures high-voltage testing and related electrical measurement equipment, including AC/DC hipot testers, partial-discharge testers, and circuit-breaker testers. The supplier reports ISO9001:2015 and ISO14001:2015 certifications, three production lines, 6–10 quality-control staff, and eight years of R&D-engineer experience; another statement reports 18 technicians in its R&D team. It serves multiple overseas markets and accepts LC and T/T payment terms, with stated one-month lead times in both peak and off-peak seasons. Evidence supports established technical and manufacturing capabilities, but after-sales service, customization, and specific customer cases are not sufficiently documented.

Supplier typeThe supplier is identified as a limited company, a factory, and a manufacturing enterprise located in Wuhan, China. Its business focuses on instruments, meters, electrical and electronic products, particularly high-voltage testing equipment.

CertificationsThe supplier explicitly reports ISO9001:2015 and ISO14001:2015 certificates, while another company description confirms ISO9001 quality management certification and high-tech enterprise qualifications. These statements provide direct evidence of formal quality and environmental management credentials.

R&D capabilityThe supplier reports successive development of multiple high-voltage testing products, participation in high-voltage and energy-saving projects with State Grid-related organizations, research institutions, and Wuhan University, and an R&D team described as 18 technicians. These are explicit indicators of product-development and technical innovation capability.

Production capacityThe supplier operates as a factory with three production lines, 6–10 quality-control staff, a 2,712 m² manufacturing plant, and stated one-month order fulfillment in both peak and off-peak seasons. It also reports self-operated import and export rights and serves several overseas markets, supporting a positive assessment of production and delivery capability.

Product Q&A

Q:What types of transformers can this tester measure?

It is suitable for all kinds of transformers, including Z-type, rectifier, electric furnace, phase-shifting, traction, and Scott/invert-Scott transformers.

Q:Does the device support three-phase testing?

Yes, it features a true three-phase test function. It uses single-phase power input to internally synthesize a three-phase standard sine wave signal source.

Q:How does the blind test function work?

It requires no wiring mode or group selection. It automatically switches the wiring mode and measures Y/* or */Y transformers without external short circuits.

Q:Can the device measure tap changer positions?

Yes, you only need to input the rated ratio once. The device will automatically calculate the ratio error for each tap position without repeated input.

Q:Is the device portable and suitable for field use?

Yes, it is lightweight (about 3kg) and has an optional internal rechargeable battery, allowing tests to be completed without any external power supply on site.
