Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›The Current Transformer Field Calibrator from Wuhan GDMK Electric Co., Ltd. is a portable instrument designed for on-site verification of current transformers in substations and power plants. It operates without external standard transformers, using an internal equivalent voltage transformer with 0.05 level accuracy to measure ratio and no-load error. The device employs recursive error calculation to combine impedance and admittance measurements into a complete transformer error profile.
The calibrator uses multi-frequency excitation (45 - 65 Hz) to minimize interference from power frequency harmonics, a critical feature for reliable field use. It supports input ranges from 5A/5A to 25000A/5A and 5A/1A to 6300A/1A, covering most industrial and utility applications. The instrument is built for rugged environments with a protective housing and internal battery backup, though no IP rating is specified in the listing.
This device is used by utility inspection teams, electrical contractors, and calibration labs that require compliance with DL/T 448-2000. Buyers typically need units with documented calibration certificates and software export capability. Packaging is a padded transport case. Delivery is FOB Wuhan Port. Lead time and MOQ are not stated; buyers must request these directly from the supplier.

Before ordering, verify the device complies with DL/T 448-2000 and SD109 for field calibration. Request the calibration certificate and confirm traceability to a national metrology institute. Ensure the device supports your local power frequency and that the internal voltage transformer matches your current transformer’s ratio range. Do not accept units without documented compliance evidence.
Confirm Incoterms - likely FOB Wuhan Port - and whether export documents are included. Lead time is not stated; request a written estimate of 15 to 30 days after payment. Payment terms are typically 30% advance and 70% against shipping documents. Ensure the commercial invoice includes HS code 9030.33 for accurate customs classification.
Upon delivery, inspect the unit for physical damage and test it with a known transformer to verify accuracy within 0.05%. Request the user manual, calibration software, and any firmware updates. Retain all documentation for audit purposes, as utilities require proof of calibration traceability. For orders over five units, consider a third-party inspection to validate performance before final payment.
