Transformer DC Resistance Tester must be tested for their delivery, installation and handover, regardless they're semi-finished or finished transformers. It's also indispensable in preventive tests for power sector. In this way, manufacturing defects like coil material, welding, loose connection, lack of strands and disconnection can be detected and hidden dangers after it's put into use can be predicted. This DC resistance tester is developed by taking full use of our technical advantages in order to meet the needs of rapid measurement of transformer DC resistance. Integrating functions of three-phase tests (Yn, Y, △) and degaussing function, this new generation quick-testing device is ideal for measuring DC resistance of large transformers. Boasting a large true color high-resolution LCD screen, full-touch operation, it's simple and intuitive to use on site.It's fast to test with high accuracy and wide measurement range.

1. Yn-type, Y-type and △-type winding can be tested in the same way as three phases, and their unbalance rate can be calculated.
2. Numerous on-site and off-site test demands of almost all transformers can be met with power supply of maximum output current being 20A, measurement range 0-200Ω, and the integration of degaussing function.
3. It can assist people to judge test data stability and prevent data misreading as resistance change rate within 5s, 15s and 30s can be automatically calculated during tests.
4. Numerous protections against back electromotive force, disconnection and power failure.
5. Equipped with a thermal printer, supporting 200 items of data storage locally and mass data storage in USB disks.
6. Comfortable and convenient user experience with fresh and simple 7-inch industrial true color screen, supporting operation by full touch control.
1. For testing winding of no-load regulating transformers, don't switch off no-load tap changer during tests or power discharging.
2. Don't disconnect test wires and cut off power switch during tests or power discharging.
3. During transformer tests, winding of the non-test side must be in open circuit.
