Harmonic analysis of current waveforms using optical current sensor

Michie, W.C. and Cruden, A.J. and Niewczas, P. and Madden, W.I. and McDonald, J.R. and Gauduin, M. (2002) Harmonic analysis of current waveforms using optical current sensor. IEEE Transactions on Instrumentation and Measurement, 51 (5). pp. 1023-1026. ISSN 0018-9456

This work reports on the research and development of an optical current sensor for harmonic analysis within the electricity supply network. The device has a measurement capability, limited by the sampling frequency of the A/D converter, to around 20 kHz. We report on experimental verification of these measurements up to the 80th harmonic (4 kHz).
