T3RC Rogowski Coil Current Probes

Teledyne LeCroy's Test Tools' Rogowski current probes offer a broad range of products covering a wide frequency span and current measurement ranges for maximum application coverage while being easy to use in difficult to reach parts of the circuit. The flexibility of the probe sense coil means that measurements can often be made without modification to the circuit under test, giving more accurate results while remaining isolated with very low insertion load of only a few pH.

The inclusion of both battery power and wall plug operation means that the Teledyne Test Tools Rogowski current probes work as well in the field as they do on the bench. The T3RC0300-UM features their smallest cross-section sense coil at only 1.7 mm. This ideally lends itself to embedded power applications where it is necessary to probe around the leg of power components, such as inductors, capacitors, or switching devices as small as a TO220 MOSFET.

The T3RC0600-HF and T3RC3000-HF are general purpose Rogowski probes covering applications up to 600 A and 3000 A, respectively. Extended high-frequency coverage, 5 kV peak insulation, and wide operating temperature range from -40°C to +125°C make them ideally suited to both general-purpose as well as wide temperature environments.

The T3RC3000-LF and T3RC6000-LF Rogowski probes offer an extended low-frequency performance down to less than 1 Hz. The low-frequency performance means that the maximum droop on low-frequency pulses is typically 0.1%/ms or less while offering Teledyne's highest level of peak insulation of 10 kV and wide operating temperature range of -20°C to +100°C.
