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).
