The PRIME 600 is a new and advanced generation of micro ohmmeter It is the only micro ohmmeter in the market that integrates both the contact resistance and the dynamic resistance measurement (DRM) for cost-efficient condition evaluation of contacts in SF6 and vacuum type circuit breakers; PRIME is a high current micro-ohmmeter that provides true pure DC with smart control up to 600 A, a wide measurement range with high power, dual ground testing process, thermal printer, touch display, pre-defined test modes and automatic reporting. Description The use of micro ohmmeters with 4-wire measurement method is a common procedure in the power field for low resistance measurements (in micro ohms and milliohms range), with the purpose of detecting and preventing future problems; it is performed in breakers, switchgear, busbars joints, switching contacts and critical connections, as well as also used in any other metallic connection checks of other installations in different industries. The PRIME 600 is a micro ohmmeter that integrates both the contact resistance and the dynamic resistance measurement (DRM) as stand-alone unit; the dynamic resistance test, which is essential in analyzing the wear of the arcing contacts in SF6 and vacuum breakers, is a function never found before in micro-ohmmeters, so that with the PRIME is not required to combine several equipment for the complete static and dynamic resistance analysis, becoming an ideal option for circuit breaker testing. The PRIME plot the DRM time/resistant curve that describes the resistance changes on the measured spot throughout a few milliseconds, for detecting contact anomalies and wear;
