Product Details

 The intelligent loop (contact) resistance tester (contact resistance tester) is designed based on the new electric power implementation standard DL/T845.4-2004, combining high-frequency switching power supply technology and digital circuit technology. It is suitable for measuring the loop resistance of switch control equipment. Its test current adopts the DC 100A and 200A recommended by national standards. The loop resistance can be directly measured at a current of 100A, or directly measured at a current of 200A, and the final test results are displayed digitally. The instrument has accurate measurement and stable performance, meeting the requirements of on-site high-voltage switch maintenance and loop resistance testing in power and power supply departments.
