The definitive description was given by Walter Rogowski and W. The lossy integrator will reduce the effects of offset voltages and set the constant of integration to zero.

A Rogowski coilnamed after Walter Rogowskiis an electrical device for measuring alternating current AC or high-speed current pulses. 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.

The whole assembly is then wrapped around the straight conductor whose current is to be measured. They are also used in short-circuit testing of electric generators and as sensors in protection systems of electrical plants.

From Wikipedia, the free encyclopedia. This type of coil also has some disadvantages over other types of current transformers.

Inoltre, in tal modo si evita che la bobina possa “circuitare” indebitamente la corrente sotto misura. Views Read Edit View history. Electrical test royowski Walter Rogowski. Il dispositivo consiste di un cavo conduttore ordinatamente avvolto in foggia elicoidale su un supporto flessibile, per formare una bobina solenoide di bobinq adeguata. They are immune to external AC magnetic fields and DC magnetic fields. 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.

This page was last edited on 22 Julyat 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.

It consists of a helical coil of wire with the lead from one end returning through the centre of the coil to the other rogowwki, so that both terminals are at the same end of the coil. The winding density, the diameter of the coil and the rigidity of the winding are critical for preserving immunity to external fields and low sensitivity to the positioning of the measured conductor.

The inductance of a toroid is [6]. The output is often integrated so the output is proportional to the wire’s current:. Retrieved from ” https: Webster, Halit Eren ed.

In other projects Wikimedia Commons Wikipedia. The difference from the traditional Rogowski coil is that the sensor can be manufactured using a planar coil rather than a toroidal coil.

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 in order to provide an output signal that is proportional to current.

Views View Edit History. This type of coil has advantages over other types of current transformers. In order to reject the influence of conductors outside the sensor’s measurement region, these planar Rogowski current sensors use a concentric coil geometry instead of a toroidal geometry to limit the response to external fields.

The whole assembly is then wrapped around the straight conductor whose current is to be measured. Rogowski coil lub Rogowski inductorniem. Electromagnetic coils Electrical test equipment.
