10KV-500KV Transformer Maintenance 10A Transformer Winding Coil DC Resistance Tester
Latest Shipping Pictures
Introduction:
1.It is applied to measure the DC resistance of inductance circuit such as power transformer coil, current transformer coil and so on.
2.Also the tester could be applied to measure the cable resistance in 4-wire mode.
3.DC resistance measurement
4.Discharge the energy automatically when test is ended
5.Print the test results by micro printer
6.When the transformer is cross-connected, overhauled or some of its switches are changed, direct current resistance testing of the transformer winding is a must...
7.In general, to measure the transformer winding or large power output inductor equipment, the traditional electrical bridge method and pressure drop method require much time and energy. Thus, to Shorten the measurement time and reducing the workload of testers, our company developed rapid direct current resistance tester.
8.Which is designed with new power supply technology and stable performance, fast measurement, compact, easy to use, high accuracy, good data reproducibility.
9.It is an ideal piece of equipment for measuring transformer windings and large power output inductor equipment.

Example of how you might use a transformer winding coil DC resistance tester:
- Connect the tester to the transformer winding you want to measure.
- Set the test current as needed or let the tester select it automatically.
- Start the test and wait for the tester to measure the DC resistance.
- Once the test is complete, the tester will display the DC resistance on its LCD screen.
- You can then save the measurement data in the tester's built-in data storage for future reference.
