HZ2181X 10A Tester di resistenza dell'avvolgimento CC con trasformatore trifase

Mar 08, 2022

HZ2181X 10A 3 Phase transformer DC resistance test instrument is a new instrument which designed for quick test of high-capacity transformer DC resistance with magnetic assist method.The method can test DC resistance of core five-limb and delta connected in the low voltage side of transformer quickly and accurately. It can be completed one time for normal YNd connected transformer,and there are different test methods for different type windings which improves greatly test speed.The instrument completes the whole process by MCU,which has perfect functions of protecing back-EMF and anti-interference on the scene, also has functions of storeing data with U-Disk, printing and communicateing with computer,protecting to avoid wrong connection AC380V. The instrument is a successor in level of 220kv-500kv transformer dc resistance test.
