Description
Overview
GAOTek contact resistance tester is crucial in applications where a high current passes through a pair of mechanically independent metallic contacts, as it is imperative that the resistance remains as low as possible. Any increase in resistance can lead to additional degradation, as I2R losses will cause local heating of the contact surfaces. Weshine invented range of micro-ohmmeters measure both steady state and dynamic low resistance values. With test currents up to 600 A available, logging and trending are also available on some models. We ensure that our Contact Resistance tests sets are portable, making them suitable for field measurements. Our contact resistance testers’ portability makes them ideal for a vast range of resistance testing across the entire LV, MV HV and EHV spectrum.
