Product Desciption
Portable Automatic Loop Contact Resistance Tester for High Voltage Switch
The tester is the special test equipment for measuring the contact resistance and loop resistance of some devices such as switch, circuit interrupter, and transformer and so on. It adopts the typical four-wire method of measurement which helps get the DC resistance through the following steps: outputting a DC current, applying the current to the tested body by linking its two terminals, and measuring the voltage drop when the current goes through the tested body, then dividing the current by the voltage. In addition, it mainly consists of constant current source, preamplifier, A/D converter, indicating device and so on. It is designed according to IEC62271
