Current Transformer Field Tester
The Wuhan GDMK Electric Co., Ltd. Current Transformer Field Tester is designed for on-site calibration of current transformers without requiring external standard transformers, load boxes, or primary cables. It operates within a test range of 5A5A to 25000A5A or 5A1A to 5000A1A, supporting secondary loads from 2.5 VA to 300 VA at power factors of 0.8 to 1.0. The device measures current transformer accuracy classes 1.0, 0.5, 0.5S, 0.2, and 0.2S, with a measurement error of 5.0% for resistance and admittance. Its 0.05S accuracy level meets industry benchmarks for field calibration tools.
The instrument uses a recursive method to determine current transformer error and a potential difference method for voltage transformer evaluation. It is built with large-scale electronic circuitry compliant with Chinese national testing protocols, ensuring reliable performance under field conditions. The unit weighs 10 kg and has dimensions of 460 mm length, 375 mm width, and 183 mm height, making it portable for field use. Power consumption is rated at 20 VA, suitable for standard portable power sources.
This tester is used by utility maintenance teams, industrial plant engineers, and calibration laboratories in China and export markets for verifying metering accuracy in substations and distribution networks. Buyers typically require confirmation of calibration traceability and compliance with IEC 60044-1 or GB/T 20840.2 standards. Packaging includes a protective case and calibration certificate. Lead time and Incoterms vary by order volume and destination port; buyers must confirm these directly with the supplier.

Sourcing Current Transformer Field Tester from Wuhan GDMK Electric Co., Ltd. - China Import Guide
Before ordering, verify the tester’s calibration certificate is traceable to a national metrology institute and confirm it matches the IEC 60044-1 or GB/T 20840.2 standards. Request test reports showing error measurements under actual load conditions, not just theoretical specs. Ensure the device has been tested for electromagnetic compatibility in industrial environments, as interference can affect field accuracy.
Confirm Incoterms such as FOB Wuhan or CIF destination port, and clarify whether import duties and local certification are included. Lead time is not stated; typical delivery for this equipment ranges from 4 to 8 weeks after payment. Ask for packaging details - the unit should be shipped in a shock-absorbing case with humidity control to prevent internal component drift during transit.
Perform a visual inspection upon receipt for physical damage. Test the device under load using a known reference transformer to verify its 0.05S accuracy. Check that all ports, connectors, and displays function correctly. Request the original calibration report and user manual. Retain a sample of the calibration data for audit purposes, especially if the device will be used in regulated utility or industrial compliance programs.
