 Intelligent Loop Resistance Tester

According to the requirements of the new "Power Equipment Handover and Preventive Test Procedures", the test current for measuring the conductive loop resistance of various switchgear shall not be less than 100A/200A. In response, our factory has developed a new generation of intelligent loop resistance tester products in accordance with the new procedures. This product is suitable for testing the main contact resistance of high and low voltage switches, as well as the DC resistance of high and low voltage cable lines.

The HLY-III Intelligent Loop Resistance Tester adopts 100A/200A constant current output. The output voltage reaches 10V (2-3 times that of conventional instruments), allowing the use of thin test leads, greatly reducing the labor intensity of field testers. The entire testing process is automatically controlled by a single-chip microcontroller, with high precision and good repeatability. Single-button operation makes it simple and easy to use, and test data is displayed on an LCD. Suitable for different working environments.
