Pico TA325 Current Probe

Pico TA325 Current Probe

30/300/3000 A AC 3-phase flex current probe, BNC connector

The TA325 is a 3-phase 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.

When using the TA325 with a PicoScope 4444 differential scope, ensure that you purchase three TA271 D9-BNC adaptors. These can be found under the Accessories tab on this page.
