DRT Transformer DC Winding Resistance Tester is a must-test item for semi-finished products in finished transformer manufacturing, finished product testing, installation, overhaul, change of tap-changer, handover test and preventive test in the 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. In order to meet the needs of rapid measurement of transformer DC resistance, our company developed the DC resistance fast tester. The instrument adopts new power supply technology and features small size, light weight, large output current, good repeatability, strong anti-interference ability and perfect protection function. The whole machine is controlled by high-speed single-chip microcomputer, with high degree of automation and automatic discharge and discharge alarm function. The instrument has high test accuracy and easy operation, and can realize rapid measurement of the direct resistance of the transformer.
Features:
1. The whole machine is controlled by high-speed single-chip microcomputer, with high automation and easy operation.
2. The instrument adopts new power supply technology, with many current gears and wide measuring range, suitable for DC resistance measurement of large and medium-sized transformers.
3, the protection function is perfect, can reliably protect the impact of the back EMF on the instrument, and the performance is more reliable.
4. with an audible discharge alarm, clear discharge indication, reduce misuse.
5. the response speed is fast, the on-load tap-changer can be directly converted in the measurement state, and the instrument automatically refreshes the data.
6. intelligent power management technology, the instrument works in the minimum power state, effectively saving energy and reducing heat.
7. 65X240 dot matrix ultra-small pixel point 65K LCD displayer
8. the instrument comes with a perpetual calendar clock and power-down storage, can store 1000 group of test data, can be consulted at any time
9. the instrument is equipped with RS232 (reserved interface) and USB interface (U disk storage).
