Product Overview

This professional testing equipment is developed in strict accordance with the new regulatory requirements for preventive tests of electrical power equipment. Its core function is to conduct contact resistance tests on various switchgear devices. For accurate and reliable test results, the equipment requires a test current of at least one hundred amperes (100A) and a continuous current supply time of not less than one minute. In addition to switchgear testing, it can also be widely applied to the resistance measurement of busbars, welded joints, electric wires and cables in power systems.
