This paper presents design and construction of an impulse current measuring system based on a Rogowski coil with a non-inverting active integrator. The developed measuring system was designed for measurement of millisecond impulse currents. The comparative measurements of the same Rogowski coil with various integrators and of a non-inductive shunt resistor were carried out in an HV Laboratory. In...
This paper presents design and construction of an impulse current measuring system based on a Rogowski coil with various types of integrators, a conventional RC integrator, a compensated RC integrator, and an active integrator. The developed measuring systems were designed for measurement of switching impulse current waveform used in a residual voltage test of arresters. The comparative measurement...
