TA326

Pico Technology - TA326

The TA326 is an AC current probe utilizing 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 probes provide a 3 V full-scale AC output proportional to the current being measured with three selectable ranges: 30 A, 300 A and 3000 A.
