The device is a Current Transformer volt‑ampere characteristic tester designed for laboratory and field verification of CT/PT performance. It can generate a test voltage from 0 V up to 2500 V and a current up to 20 A while operating from a single 220 V AC supply. The tester automatically records VA curves, DC resistance, ratio, polarity, 10 % error curve, angle difference and ratio difference without manual tracing. It also supports secondary load testing, CT current testing and PT AC withstand voltage testing for both casing CT and GIS installations.
The instrument is built around a solid‑state voltage source and uses precision shunt resistors to achieve typical accuracy of 0.5 % on the volt‑ampere curve. Its temperature operating range is typical 0 °C to 50 °C, matching most utility laboratory environments. Safety compliance follows IEC 61010‑1 class II protection, and the front panel offers USB data export for easy integration with test software. The unit is supplied in a rugged metal enclosure suitable for repeated bench use.
Electrical utilities, protection relay manufacturers and testing laboratories purchase this tester to certify current transformer compliance before shipment. Importers should request the supplier’s calibration certificate, confirm the minimum order quantity and negotiate Incoterms such as FOB Wuhan port. Payment terms and lead‑time details are not disclosed in the listing and must be verified directly with Wuhan GDMK Electric Co., Ltd.

Before placing an order, verify that the tester complies with the IEC 61010‑1 safety standard and that a recent calibration certificate is available. Ask the supplier to provide a test report showing the 0.5 % accuracy claim across the full 0‑2500 V range. Confirm that the 220 V AC power requirement matches the voltage supplied at the receiving port in China.
Discuss logistics early, specifying whether the shipment will be FOB Wuhan port or CIF another destination. Inquire about the typical lead‑time for production and any required pre‑shipment inspections. Clarify the preferred Incoterms and whether the supplier accepts payment by telegraphic transfer, letter of credit or other methods, as these details are not listed.
Arrange a third‑party inspection to check enclosure integrity, USB connectivity and functional performance against the listed specifications. Request the supplier’s test data files and a declaration of conformity for export. Keeping records of the inspection report and calibration certificate will smooth customs clearance and downstream quality assurance.
