Abstract :
We demonstrate exceptional power measurement linearity over a wide dynamic range with an optical current transducer and power meter. The accuracy is about ±0.2 % from 0.1 % to 150 % of the CT´s rated current when the optical current transducer output has an artificial dither. We also present the latest testing of our current transducer, which demonstrates mechanical robustness and stability over extreme environmental conditions.
