Single Phase 10A Current Transformer Testing Equipments DC Resistance Tester

Power Transformer Single Channel DC Resistance Tester ,Single Phase 10A Test Current Output

I. Products Description and Application 

The DC resistance of the transformer is a must-test item for the semi-finished products in the transformer manufacturing, the factory test, the installation, the handover test and the preventive test from the power sector. It can effectively find some defects caused from the selection of the transformer coil, the welding, the loosening of the joints, the lack of strands, the wire breakage, etc.  and also hidden dangers after running. In order to meet the needs of rapid measurement of DC resistance of transformers,Model FK-10A DC resistance tester is performed  DC resistance measurement for 35KV and below power transformer Power Transformer it with seven optional test current gears as auto selection,10A, 5A,1A,200mA,40mA,<5mA and 0.5mΩ-100KΩ test range.

II. Features

1. Controlled by high-speed single-chip microcomputer, with high automation and easy operation.English operation menu.

2, Using new power technology, current gear position, wide measuring range, can automatically select the test current according to the load.

3, 320*240 dot matrix 65K true color LCD touch screen, clear display under strong light, touch screen / button dual operation way.

4, RS232 and USB interface, can communicate with the computer and U disk storage.

5, The protection function is perfect, can reliably protect the impact of the back EMF on the instrument, and the performance is more reliable.

6, With discharge sound alarm and screen prompts, clear discharge indication, reduce misuse

7. The response speed is fast, the measurement data is stable, and the data is automatically refreshed during the test.

8, Intelligent power management technology, effectively reduce the internal heating of the instrument, saving energy.

9, No power down clock and no power down memory, can permanently save data.

10. AC/DC working mode, can be used at the site with or without utility power.

11. Seven optional test current gears as auto selection,10A, 5A,1A,200mA,40mA,<5mA
