Transformers are core equipment in power systems, and their long-term reliable operation is critical to the stability and reliability of the entire system. Transformer DC resistance is a mandatory test item for semi-finished products, finished product factory tests, installation, handover tests, and preventive tests conducted by power departments. It effectively detects manufacturing defects such as improper coil material selection, welding issues, loose connections, missing strands, and wire breaks, as well as operational hazards. To meet the demand for rapid DC resistance measurement, this company has developed this Transformer DC Resistance Tester using proprietary technical expertise. The instrument supports three-phase simultaneous measurement of A0, B0, and C0 phase DC resistance for Y-type windings with a neutral point, greatly saving test time. Featuring a 5.7-inch large LCD display, membrane keyboard operation, and a compact portable design, it delivers fast, accurate, and wide-range measurement for reliable field use.

Designed for distribution transformer maintenance teams, power supply bureau field technicians, and small and medium transformer repair workshops that need a portable, rugged DC resistance tester for routine field measurement. With three-phase simultaneous measurement of A0, B0, and C0 windings, back EMF protection, and automatic discharge indication, it is tailored for safe, efficient on-site testing of distribution and medium transformers. Unlike touch-screen instruments with magnetization capability optimized for large transformer rapid testing, this model emphasizes portability, anti-vibration, and straightforward keyboard operation for field crews.
