Abstract
This paper presents design and calibration of a self-integrating Rogowski coil to measure high impulse currents. This coil is wound in single-, double-, and triple-layers by a coaxial cable without its polyvinyl chloride (PVC) jacket “sheath.” Overdamped unidirectional and oscillatory impulse currents are generated up to 7 kA and measured by different methods, namely, a commercial impulse current transformer (ICT), a commercial Rogowski coil (CRC) and the newly designed self-integrating Rogowski coil. The output voltage linearity of the designed self-integrating Rogowski coil with different layers is checked using different stages of the impulse-current generator, linear and nonlinear loads, and coil termination resistances. It is found that at a termination resistance of 1.1 Ω, satisfactory impulse current waveforms are measured by taking the commercial impulse current transformer as a reference signal. Results reveal that the magnitudes of measurement errors for the current peak, and front and tail times are
