200A Loop Resistance Tester ,IEC 62271 Contact Resistance Tester for High Power UPS System Safety Inspection

GDHL-200A circuit resistance tester is based on GB1984 and IEC62271 standards, and adopts a new digital switching power supply technology that can directly produce 200A DC current output to the circuit breaker being tested.
The test results are quickly measured by the 4-wire method to determine the contact resistance of the circuit and displayed on the LCD screen. In addition, the device is equipped with a micro printer, and all results can be directly printed using the tester. The test results can not only be saved in 100 sets on the instrument memory, but also uploaded to a PC through the RS232 interface for storage.

Introduction


Circuit resistance tester adopts the national standard requirement of 200A DC constant current to continuously measure resistance with an accuracy of 0.5% RGD+0.05% FS. Not only can it be tested in harsh outdoor environments with temperatures ranging from -10 ℃ to 40 ℃, but it can also work in tropical rainforests with relative humidity<80%.

The equipment is commonly used to measure the contact resistance of conductive circuits such as high-voltage switches, circuit breakers, bus ducts, cable joints, etc., which can effectively prevent local overheating, burning or power accidents caused by poor contact.
