The Rogowski coil is defined as an electrical device that is used to measure alternating current (AC). It is also used to measure the high-speed transient, pulsed current or sinusoidal current. A Rogowski coil is an evenly wounded coil with N number of turn and constant cross-section area A. There is no metal core in a Rogowski coil. The end terminal of the coil is returned through the central axis of the coil to another end. Therefore, both terminals are at the same end of the coil.
