Pico TA326 30/300/3000A AC Flex Current Probe with BNC Connector The TA326 is an AC current probe utilising the Rogowski coil principle, used to measure AC current up to 3000 A when used with oscilloscopes, recorders or data loggers. The flexible probe allows current measurements on hard-to-reach conductors. Rogowski coil technology has a couple of advantages over CT (current transformer) technology: when measuring multiple phases, the phase difference is small and predictable for higher frequency harmonic analysis applications; also, Rogowski coils do not have magnetic materials to saturate and so have excellent linearity. The probe has three user selectable ranges; 30 A, 300 A and 3000 A.​The probes provide a 3 V full-scale AC output proportional to the current being measured with three selectable ranges. Features and Benefits 1000 V RMS, Category III, 600 V RMS, Category IV Pollution Degree 2 (probe and integrator) 30 V maximum between output and ground RoHS and WEEE compliant Rated for continuous use
