More recently, low-cost current sensors based on the principle of a Rogowski coil have been developed.

They are also used in short-circuit testing of electric generators and as sensors in protection systems of electrical plants. Powered by GDPR plugin.

Il dispositivo consiste di un cavo conduttore ordinatamente avvolto in foggia elicoidale su un supporto flessibile, per formare una bobina solenoide di lunghezza adeguata.

The main advantage of the planar Rogowski current sensor is that the coil winding precision that is a requirement for accuracy can be achieved using low-cost printed circuit board manufacturing.

It consists of a helical coil of wire with the lead from one end returning through the centre of the coil to the other end, so that both terminals are at the same end of the coil. Contact Us Power Product Page.

The whole assembly is then wrapped around the straight conductor whose current is to be measured. A Rogowski coilnamed after Walter Rogowskiis an electrical device for measuring alternating current AC or high-speed current pulses. There is no metal iron core.

Since the voltage that is induced in the coil is proportional to the rate of change derivative of current in the straight conductor, the output of the Rogowski coil is usually connected to an electrical or electronic integrator circuit to provide an output signal that is proportional to the current.

In practice, an instrument will use a lossy integrator with rogows,i time constant much less than the lowest frequency of interest.
