Analysis of Rogowski Coil with Passive Compensation

Abstract:

The influences of the position of the primary conductor to the mutual inductance of a test Rogowski coil were studied. The test results show that the deviation of the mutual inductances can not be neglected. Manufacturing variations affect the mutual inductance much and make the coils have bad interchangeability. A potentiometer is suggested to be placed in the coil to provide a passive compensation, enabling coil manufacturers to produce coils with uniform performance increasing interchangeability while reducing manufacturing complexity. The error analysis shows that the coil with potentiometer has very good performance.
