4.2.9 Rogowski Coil

The special kind of helical coil sensor uniformly wound

on a relatively long nonmagnetic circular or rectangu-

lar strip, usually exible (Figure 4.35), is commonly

known as the Rogowski coil, after the description

given by Rogowski and Steinhaus in 1912 (Rogowski

and Steinhaus 1912). In certain applications, this coil,

known as Rogowski–Chattock potentiometer RCP, is used

for measurement of magnetic eld strength. Indeed,

the operating principle of such a coil sensor was as

rst described by Chattock in 1887 (Chattock 1887) (it is

not clear if Rogowski knew t ...
