Intelligent Loop Resistance Tester

Per the new "Power Equipment Handover and Preventive Test Regulations," switchgear conductive circuit resistance measurement requires a test current of no less than 100A. We have developed a new generation intelligent loop resistance tester suitable for testing HV/LV switch main contact resistance and HV/LV cable line DC resistance. The JD-100 intelligent loop tester uses 100A constant current output with maximum voltage up to 10V (2-3 times conventional instruments), enabling thinner test leads and significantly reduced field labor. The entire test process is MCU-controlled with automatic execution, high precision, good repeatability, single-key operation, and LCD display. Suitable for various working environments.
