Abstract

Two very simple electric-optic hybrid schemes which demodulate the output from a conventional current transformer (CT) are presented. The first scheme would be very useful for indicating whether the conductor was carrying current or for making measurements within an accuracy of 10% at extremely high potentials. Whilst the second scheme, with a demonstrated minimum detectable signal of 0.32 Amp/(root)Hz, offers low cost accurate current measurement at high potentials.
