DC Resistance Tester (abbreviated as: DC Resistance Tester) is an essential instrument in transformer manufacturing for semi-finished and finished product factory tests, installation, major repairs, after changing tap changers, handover tests, and preventive tests in power departments. It can meet the needs of transformer DC resistance measurement, and for large transformers, it can also detect the welding quality of winding joints and whether there are inter-turn short circuits in the windings.
Many people, when using a DC resistance tester for the first time, usually wonder if this type of testing instrument is difficult to use.
DC resistance testers are also divided into different types according to transformer levels. For example, the detection of large transformers uses the GDZRC-100A large transformer DC resistance test device. If you need to test distribution transformers, mutual inductors, reactors, generators, motors, and other test objects, you can choose the GDZRC-10Q DC resistance quick tester. These two DC resistance testers each have their own characteristics and are very simple and convenient to use.
The GDZRC-100A can detect whether the contact at each position of the voltage tap changer is good, whether the actual position of the tap changer matches the indicated position, whether the lead wires are broken, and whether multi-strand parallel windings have broken strands. The whole machine is controlled by a high-speed microcontroller, with a high degree of automation, and has automatic discharge and discharge alarm functions. The instrument has high testing accuracy and is easy to operate, enabling fast measurement of transformer DC resistance.
