Transformers act as the heart of power systems, and their sustained, dependable performance is fundamental to maintaining the overall stability and reliability of the entire grid. DC resistance testing is an essential procedure for transformers — required at every stage from semi-finished and finished product factory checks to installation, handover, and routine preventive maintenance. This test pinpoints critical issues including substandard coil materials, poor welding, loose joints, missing conductor strands, and wire breakages during manufacturing, as well as hidden risks after the transformer is put into operation. To address the need for efficient DC resistance measurement, this company has engineered the Transformer DC Resistance Tester using proprietary technical expertise. This next-generation tester combines the magnetizing method, three-phase measurement (Yn, Y, and Δ), and demagnetization, making it ideal for measuring DC resistance in large and medium power transformers. Its true-color high-resolution large LCD screen, touch operation, and jog dial ensure effortless on-site use, with intuitive menu guidance and a single wiring setup completing all DC resistance tests with high speed, precision, and a broad measurement range.

Designed for transformer manufacturing factory QC and outgoing testing departments that must verify winding DC resistance during production and before shipment. With multiple safety protections including line breakage, back EMF, and power failure protection, the XHZ1320AX enables continuous, safe factory testing of semi-finished and finished transformers. Unlike instruments positioned for field preventive maintenance, this configuration is optimized for production-line and outgoing quality verification where safety interlocking and rapid measurement throughput are priorities.
