CT/PT Calibrator
The CT/PT Calibrator is an intelligent instrument designed to test error and impedance admittance of current transformers (CT) and potential transformers (PT). It complies with the Chinese national verification regulations JJG 313‑94 for CTs and JJG 314‑94 for PTs, providing the accuracy required for utility and laboratory environments. The device features an LCD display for real‑time readout and supports both manual and automated test sequences.
Typical measurement ranges span from 0.1 % to 5 % error, with an accuracy class of 0.2 % as commonly required for transformer verification. Power is supplied from a universal 110‑240 V AC source with an internal battery backup that maintains operation during brief outages. The unit usually connects to external systems via RS‑232 and USB ports, allowing data export for record‑keeping and analysis.
Electrical utilities, transformer manufacturers and calibration laboratories are the primary buyers of this equipment. The calibrator is mounted in a standard 19‑inch rack, occupying a 1U height, which fits most test bays. Pricing, minimum order quantity and delivery lead time are not listed; prospective purchasers should request a detailed quotation and confirm trade conditions with the supplier.

Sourcing CT/PT Calibrator from Wuhan GDMK Electric Co., Ltd. - China Import Guide
Confirm that the calibrator carries an up‑to‑date certification against JJG 313‑94 and JJG 314‑94, and ask for a copy of the calibration report that details traceability to national standards. Verify the measurement range and accuracy class match the requirements of your testing protocol before finalising the purchase.
When arranging shipment, note the 1U, 19‑inch rack form factor and ensure the packaging protects the LCD and internal electronics. Because the listing does not state Incoterms or lead time, request a formal quotation that clarifies freight responsibilities, insurance coverage and expected delivery schedule.
Perform a factory‑acceptance test that checks the device’s error measurement across the 0.1 %‑5 % range, validates the RS‑232 and USB communication functions, and confirms the battery backup operation. Retain the calibration certificate and any test logs as part of your quality‑assurance documentation.
