Musktool-TCR10G 10A Transformer DC Resistance Tester,DC miliohmimeter,Transformer Winding Resistance Tester
INTRODUCTION
The DC resistance of transformer is a necessary test item for the factory test, installation, overhaul, change of tap changer, handover test and preventive test of power department in the manufacture of semi-finished products and finished products of transformer. It can check the welding quality of the winding joint and whether the winding has inter turn short circuit. It can detect whether the contact at each position of the voltage tap changer is good, whether the actual position of the tap changer is consistent with the indicated position, whether the outgoing line is broken, and whether there are broken strands of multi strand conductors. MUSKTOOL-TCR10G Transformer DC Resistance Tester adopts new power supply technology and has the characteristics of small volume, 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 has the functions of automatic discharge and discharge alarm. The instrument has high test precision and simple operation, and can realize the rapid measurement of transformer direct resistance. |
MAIN FEATURES
1.The whole machine is controlled by high-speed single chip microcomputer, with high degree of automation and simple operation. |
2. The new power supply technology is adopted, with many current gears and wide measurement range. The test current can be automatically selected according to the load. |
3. 480 * 270 dot matrix 65K true color LCD touch screen, clear display under strong light, support both touch screen and buttons operation. |
4. RS232 and USB interface, can communicate with computer and U disk storage. |
5. The protection function is perfect, which can reliably protect the impact of back EMF on the instrument, and the performance is more reliable. |
6. With discharge audible alarm and screen prompt, the discharge indication is clear to reduce disoperation |
7. The response speed is fast, the measurement data is stable, and the data is refreshed automatically during the test process. |
8. Intelligent power management technology can effectively reduce the internal heating of the instrument and save energy. |
9. Non power down clock and non power down memory can permanently save data. |
