Plasma and Pulsed-Power Applications

Founded in the 1930s, Japan's IWATSU is a global leading manufacturer of Rogowski coils for high-frequency, large-current applications. IWATSU Rogowski coils are widely used in power semiconductors, pulse current research, plasma pulse power, and power grid transmission and distribution industries. Rogowski coils are mainly used to measure AC current; they offer large current measurement ranges, wide frequency response, and high accuracy. Users can fully customize the coil and lead dimensions according to the size and installation location of the object being measured, with lengths ranging from one meter to over ten meters. We also provide flexible coils suitable for various complex environments, such as double-shielded Rogowski coils for use in complex electromagnetic environments, as well as various types of terminal interfaces.

Main Advantages of Rogowski Coils:

No magnetic saturation

Easy to use, simply wrap around the conductor/busbar being measured

Good insulation and voltage resistance

Ultra-wide bandwidth: 0.1Hz - 100MHz

Large measurement range: 1mA - 10MA

Flexible installation without damaging existing circuits

High stability and consistency

Accuracy up to 0.1%
