What is the DC resistance tester used to measure DC resistance and winding DC resistance values;
At present, the main types on the market are divided into single-pass and dual-channel and three-channel according to functions, and are divided into: 1A, 2A, 5A, 10A, 20A, 40A, 50A, 60A, 100A according to the current;
The main differences between DC resistance testers are: single-pass is mainly based on the load can automatically select the current, suitable for small and medium-sized transformers and voltage transformers and transformer windings and DC resistance measurement of high-power inductors, and which can be optional With battery, printer, USB interface, R232 interface and other functions;
The dual channel is designed for temperature rise measurement of three-core and five-column large transformers. It has fast charging and measuring speed, can meet the time requirement of transformer temperature rise test, and can measure two resistance values ​​at the same time.
The three-channel is an instrument for simultaneous measurement of three-phase three-phase transformer winding DC resistance. The instrument can test the three-phase of the transformer winding at the same time. The on-load tap-changer can be directly adjusted and tapped. The model can be selected according to different test items. As for the price of the DC resistance tester, the price is provided according to different selection functions.
