Mv output rogowski coil

Compared with the conventional transformer, the Rogowski coil has no core magnetic material no magnetic saturation phenomenon, so it can test thousands of amperes of current without saturation, without the risk of secondary open circuit. Because of its fast response speed and unsaturation, it can measure various complex waveforms, which is widely used in power, relay protection, resistance welding and other fields.

* Coil inner diameter can be customized according to the requirements, coil diameter 50 – 600 mm;
* Light weight, easy to carry, flexible design can be used in various irregular installation environment.
