Rogowski coil feature
Rogowski coil has better frequency reaction than normal current transformer due to low inductance and non-magnetic core. It also does not use saturation core, so it is very accurate on high primary current. These kind of sensors are better to apply specially on power measuring system which has high current of fast changing current. To measure high current, normal current transformer is usually big and heavy. In contrast, Rogowski coil is small and light, so it is simply installed as advantage.
Rogowski coil technology
The AC CT has two types of split-core & solid-core design with various utility, high reliability & Cost-effective solution for precise current measurements. The rated current range is 5 to 2400AAC and secondary output value is 0-5/10V or 4-20mADC & 0.1A/1A/5A/333mVAC/Instantaneous AC current.
