Product Description GDZRC-20U Transformer DC Winding Resistance Tester 60A Output Current Product DescriptionGDZRC series DC winding resistance tester is designed to measure DC resistance of inductive devices, such as transformers and power inductors. It has the features of fast measurement, small size and high accuracy of measurement, which is ideal equipment of measuring transformer winding and DC resistance of big power inductance equipment.Transformer DC resistance is a must-test item for semi-finished products, finished product testing, installation, overhaul, change of tap-changer, handover test and preventive test in power sector. It is possible to check the welding quality of the winding joint and whether the winding has a turn-to-turn short circuit. It can detect whether the contact of each position of the voltage tap changer is good and whether the actual position of the tap changer matches the indicated position, whether the lead wire is broken or not, and the multi-strand wire is wound. Whether there are broken shares and so on.Application Welding quality of winding contactTurn-to-turn short circuit of windingContact of tap changerFeatures 320*240dot matrix, 65k true color LCD display.High-speed single-chip control, high automation degree, easy operation.With a sound discharge alarm, the discharge indication is clear.Fast response speed. The tap changer can be converted directly into measurement status. The instrument update data automatically.The instrument adopts new power supply technology, with many current gears and a wide measuring range, suitable for DC resistance measurement of large and medium-sized transformers.The protection function is perfect, can reliably protect the impact of the back EMF on the instrument, and the performance is more reliable.With clock and power-off storage. Save up to 1000groups test data.With USB port, for USB disk storage. RS232 interface reservation.With a small printer, can print test results.
