Rogowski CWT Ultra Mini series current loops are easy to install, virtually non-interacting, ideal for confined spaces, isolated up to 1200 V and insensitive to overcurrents. They can be used to measure current curves with fast current pulses, switching edges or sinusoidal or sinusoidal current curves. Rogowski coils of the CWT Ultra Mini - series from P.E.M. are suitable for development and test tasks in devices and components of power electronics. They combine a 1.6 mm thin, flexible, insulated, easy to apply coil with the ability to accurately detect very fast current characteristics, whether sinusoidal, clocked or pulsed.
