Xinrui supplies 3125A high-voltage megohmmeter Kreutz insulation resistance tester KEW

Resistance tester is a tool for electrical safety inspection and completion acceptance of grounding engineering. Including grounding resistance tester, insulation resistance tester, DC resistance tester, surface resistance tester, and loop resistance tester. The circuit resistance tester (transformer circuit resistance tester) is suitable for testing the contact resistance value of the main contacts of high and low voltage switches, as well as the DC resistance value of high and low voltage cable lines. The intelligent circuit resistance tester adopts 100A constant current output. When the output voltage reaches 10V (2-3 times that of conventional instruments), a thin test line can be used, greatly reducing the labor intensity of on-site testing personnel. The testing process is entirely controlled by a single chip and automatically implemented, with high accuracy, good repeatability, single button operation, simple and easy to implement, and LCD display of test data. Suitable for different work environments. The grounding resistance tester is a commonly used instrument for testing and measuring grounding resistance. In recent years, due to the rapid development of computer technology, the grounding resistance tester has also incorporated a large amount of microprocessor technology. Its measurement function, content, and accuracy cannot be compared to general instruments.
The DC resistance tester is a new generation of transformer DC resistance testing instrument, which can automatically select the test current according to different models of power transformers and display the test results at a certain speed. The DC resistance tester has functions such as storage, printing, and discharge indication. It is equipped with a built-in power-off memory that can store measurement data for a long time. The use of a LCD display makes the instrument have a good human-machine interface and is a device used in DC resistance testing work
