Explanation of the functional characteristics of the transformer DC resistance tester

The transformer DC resistance tester is based on a high-speed microcontroller, using high-speed A/D converters and programmable current source technology to achieve measurement results and highly automated measurement functions. It has high accuracy, wide measurement range, stable data, good repeatability, strong anti-interference ability, and complete protection functions. The characteristics of fast charging and discharging speed. This instrument. Small in size, light in weight, and easy to carry, it is a new generation product for transformer DC resistance testing.

The DC resistance tester is small in size, lightweight, and easy to carry. It has the characteristics of rapid measurement, convenient use, and high measurement accuracy. The self check and automatic calibration functions reduce the difficulty of instrument use and maintenance, making it a device for measuring the DC resistance of transformer windings and high-power inductive equipment.

Automatically select the test current based on different models of power transformers and display the test results at a fast speed. The DC resistance tester has functions such as storage, printing, and discharge indication, and is equipped with a built-in non power-off memory that can store measurement data for a long time. The use of a LCD display makes the human-machine interface of the instrument good, making it a device for DC resistance testing work.

Function and characteristics: Adopting a high-speed 16 bit A/D converter, the measurement data is stable and has good repeatability. Automatic programmable current source technology, with a total of 1000 current levels set for the current source, is automatically controlled by an internal microcontroller based on the measured resistance, achieving a relatively wide measurement range and measurement status without the need for manual switching of current levels. The response speed is fast, and the tap changer can be directly converted during measurement. The instrument will automatically prompt, and the new resistance value will be displayed quickly.

Highly intelligent design with clever functional settings, capable of automatically detecting faults such as virtual or broken test lines. The protection function is complete and can reliably protect the impact of back electromotive force on the instrument, with automatic discharge indication function. It can display the measured current and measurement time. Intelligent power management technology can effectively reduce internal heating of instruments. Can store 120 measurement data without losing power. All Chinese character menus and operation prompts are intuitive and convenient.
