Product Description Product DescriptionTransformer Test Equipment Winding Resistance Test Set DC Resistance Detector Apply to the test for all kind of sensibility on-load DC resistance and low-voltage switcher touched resistance, cable or weld resistance of transformer, large generator, CTPT, etc. The instrument is characterized by fast test speed, high precision, intuitive display, strong anti-interference ability, small size, low power consumption, stable and reliable test data.IntroductionAs transformer is the core equipment in power system, its long-term reliable operation is of high significance to the stability and reliability of the whole system. The DC resistance of transformers 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 as well as hidden dangers after it's put into use can be detected. This DC resistance tester is developed by taking full use of our technical advantages in order to meet the needs of fast measurement of transformer DC resistance. Boasting a large true color high-resolution LCD screen and adopting touch control and jog dial, it's convenient to use on site. Featuring Chinese menu prompts, it's simple and intuitive to operate. It's fast to test with high accuracy and wide measurement range.Features1. Fast test: The maximum output charge current of the instrument is up to 1A. When measuring it can effectively compensate current inertial for large inductor and accelerate core saturation, thereby reduced the charging time and increased test speed. Its test speed is faster hundreds of times than the traditional single instrument and double bridge.2. High accuracy: The application of advanced four-terminal measurement and constant current source technology to the instrument makes the inductive load charging current hold a relatively stable value. Base on that, and the instrument with stable anti-sense capability and strong anti-interference characteristics can ensure the accuracy of measurement. And the use of imported high-quality components not only improves the measurement accuracy, but also makes the instrument have good repeatability.3. Wide measurement range: resistance measurement range 1μΩ ~ 2KΩ, wide range.4. AC and DC power supply: Attached rechargeable battery, the instrument can use AC and DC power supply. Portable design, it is easy to carry and use.
