Rogowski Coil Current Transducer [transdutor De Corrente Do Tipo Bobina De Rogowski]
, 2015 This paper presents two procedures for a Rogowski Coil design. The first, a traditional procedure, is based in an infinite length of the primary wind. In the second procedure, the current evaluation is obtained applying the Biot-Savart Law.

Influence of busbar geometry on AC current measurement using Rogowski coil
, 2008 Readout of a Rogowski coil is affected by external magnetic fields e.g. from the energizing transformer and the return current conductor. The influence of these external magnetic fields on the reading of a high precision Rogowski coil was measured.

A Rogowski-Chattock coil for local magnetic field measurements: sources of error
, 2010 A magnetic field can be measured on a space scale of a few millimeters by means of magnetic sensors, such as a Rogowski–Chattock coil. The main advantage of the Rogowski coil is its capability to measure the field strength directly at the sample surface ...

Current Sensor Based on Rogowski Coil.
RE&PQJWe have built several Rogowski coil current sensors for measuring currents in non sinusoidal systems. In this paper we present the sensor and his behavior. We have built a generator of pulses in order to test it and we compare the results between two types of coils (flexible and Printed Circuit board PCB designed) and the linearity for measuring ...

High-Frequency Model of the Rogowski Coil With a Small Number of Turns
, 2008 —In this paper, the Rogowski coil is modeled as a distributed-element transmission line. The elements in the distributed transmission line are modeled using physically based equations.
