Import Ct/Pt Tester — Buy in Bulk from Supplier in China

The APVA‑402 CT/PT Tester is a dedicated instrument for assessing the performance of current transformers and potential transformers in power systems. It carries out ratio, polarity and burden tests through an integrated LCD interface that guides the operator step‑by‑step. The unit is built with a rugged enclosure designed to resist the dust and temperature swings typical of substation environments. Its design complies with the functional requirements of utilities and maintenance teams that need reliable diagnostic data.

Typical CT testing equipment offers an accuracy class of 0.2 % and measurement ranges from 0.1 kA to 10 kA, while PT modules commonly handle up to 600 V. The APVA‑402 matches these industry standards, providing the precision needed for calibration labs. Its power input accepts 110‑240 V AC, allowing deployment in most regional facilities. The device weighs roughly 5 kg and fits within a footprint of about 300 × 200 × 150 mm, dimensions that are standard for handheld transformer testers.

Power generation plants, transmission utilities and industrial maintenance contractors use this tester to verify transformer ratios before commissioning or during routine checks. The supplier lists flexible order quantities, but exact minimums are not published, so buyers should confirm the batch size directly. Shipping can be arranged on CIF or FOB terms, and the supplier holds ISO‑type quality management recognitions, though the specific certificates should be validated with the exporter. Prospective importers are encouraged to request the latest test report and conformity documentation before finalising the purchase.
