100a circuit breaker circuit contact resistance measurement tester

RDHL-100A loop resistance tester is a high-precision, digital switch testing instrument developed by our company according to IEC standards and the latest electric power implementation standard DL/T845.4-2004 of the People's Republic of China, which fully utilizes our advantages. own technical advantages. The instrument adopts high-frequency high-power constant-current switching power supply technology, which can measure micro-ohm level contact resistance. It is widely used to measure the contact resistance and loop resistance of various switches and electrical appliances, as well as the contact resistance of cables, wires and welds. The instrument has accurate measurement data and stable performance, meeting the requirements of on-site high-voltage switch inspection and maintenance of electric power and power supply departments and loop resistance testing of high-voltage switch factories.

1. The four-terminal measurement method is used to sample voltage and current at the same time, which can eliminate the influence of connection resistance and contact resistance. 2. The operation is simple, and the test process can be completed with one key. The test current is automatically stabilized, and the test data is stable and reliable. 3. It adopts high-strength injection-molded safety shell, which is small in size and light in weight, and is suitable for outdoor portable use. 4. Imported high-reliability and high-power integrated circuits are used, so the failure rate is extremely low.
