- Abstract:
- The aim of presented work was the realization of program for the Rogowski Coil design with respect to the amplitude and shape of the measured current and parameters of circuits for output voltage evaluation. There was taken into consideration closed nonferromagnetic toroidal Rogowski Coil wound as one-layer homogenous winding. The program for Rogowski Coil design is able to calculate coil dimensions to obtain required value of mutual inductance between conductor with measured current and the sensing winding. The goal is to reach defined amplitude and time course of induced output voltage when measuring impulse current. The defined amplitude should be appropriate to the input sensitivity of evaluation circuits. There are respected many adjacent parameters, for example insulation distance between conductor with measured current and sensing winding, on the assumption that Rogowski Coil was used in high-voltage power grids. Leakage capacitances of sensing winding are not respected at the moment. The computation was verified by measurement of the harmonic current with power frequency, while dimensions and number of Rogowski Coil turns were optimized to suppress leakage capacitances.
