Import Ct Pt Analyzer — Buy in wholesale FOB from Supplier in China

The CT PT Analyzer from Wuhan GDMK Electric Co., Ltd. is a portable diagnostic instrument designed for comprehensive testing of current and voltage transformers in power systems. It performs nine tests on current transformers including excitation curve analysis, turns ratio verification, polarity marking, winding resistance measurement, secondary burden assessment, and saturation hysteresis loop characterization. For voltage transformers, it conducts turns ratio, ratio error, phase angle error, polarity, and burden tests. All measurements are captured in real time with automated error calculation against IEC and IEEE standards.

The device operates with internal signal generators and digital signal processing to measure parameters such as excitation current at 0.1% accuracy, phase angle error within ±0.1 minutes, and winding resistance down to 0.01 ohms. It supports standard CT classes like 5P, 10P, and 0.5S, and can handle secondary currents up to 5A and voltages up to 1000V. The analyzer stores reference curves for comparison and outputs reports in Microsoft Word format, enabling field engineers to document compliance without manual transcription.

This instrument is used by utility maintenance teams, transformer manufacturers, and calibration laboratories in China and Southeast Asia. Buyers typically require it for preventive maintenance of substations, commissioning of new installations, and periodic compliance audits. The unit is shipped in a ruggedized case with power adapter, test leads, and USB cable for data transfer. Delivery lead time is typically 15 to 25 days after order confirmation, and Incoterms are FOB Wuhan or CIF as negotiated. MOQ is one unit, with bulk discounts available for orders of five or more.
