Import Bct Pt Tester — Buy in wholesale FOB from Supplier in China

The BCT PT Tester from Wuhan GDMK Electric Co., Ltd is a multi-function transformer testing instrument designed for current transformer (CT) and potential transformer (PT) parameter analysis in power system applications. The device builds upon the supplier's earlier FA Series Transformer Tester platform, incorporating digital signal processor (DSP) and ARM architecture for measurement automation. It performs CT parameter analysis, CT excitation characteristic testing, ratio and polarity verification, winding resistance measurement, and transient characteristic analysis. The instrument targets utility companies, transformer manufacturers and large industrial facilities requiring periodic calibration and commissioning verification of instrument transformers.

The hardware platform combines a high-performance DSP for real-time signal processing with ARM-based control logic, an architecture common in second-generation relay test and transformer test equipment from Chinese manufacturers. Measurement functions include volt-ampere characteristic curve tracing, knee-point voltage and current detection, secondary burden simulation, and demagnetisation routines. The transient analysis capability captures CT saturation behaviour under fault conditions, relevant for protective relay coordination studies. The supplier notes 'full-featured' and 'high degree of automation' without specifying channel count, output power rating or accuracy class against IEC 61869 or IEEE C57.13 standards.

Primary buyers include state grid corporations, independent testing laboratories, transformer OEMs and large industrial plants with internal substation maintenance teams. The equipment serves both factory acceptance testing and field commissioning roles. Wuhan GDMK Electric lists no specific trade terms, MOQ or lead time, requiring direct negotiation. Buyers should confirm software language availability, firmware update mechanisms, and whether the supplier provides on-site commissioning support or remote technical assistance. Calibration certificates from CNAS-accredited laboratories should be requested to validate measurement traceability for quality-sensitive applications.

Wuhan GDMK Electric Co., Ltd is located in Jiangxia District Economic Development Zone, Daqiao New District, Huangjiahu Avenue, Wuhan 430200, China. The supplier holds a 'harbor' trust tier classification with a zero percent response rate and no recorded average response hours, indicating minimal or no platform-mediated buyer communication history. The address situates the company within Wuhan's designated economic development zone, an industrial district hosting electrical equipment and automotive suppliers. No information discloses whether this is a manufacturing facility, design office or trading operation.

The company profile omits establishment year, registered capital, employee count, annual revenue, patent portfolio, client references and specific quality certifications such as ISO 9001 or CNAS laboratory accreditation. The product description references predecessor FA Series equipment but provides no sales volume, installed base, or geographic deployment data. Buyers should independently verify manufacturing capability through factory inspection, request evidence of software copyright registration for the control system, and confirm the availability of spare parts and technical documentation in required languages. The lack of response metrics suggests direct telephone or email outreach may be necessary to establish viable commercial dialogue.
