Paper Abstract

Optical current sensors are advancing the modernization of the power grid because of the reduced costs, environmental savings, safety, reliability, and measurement fidelity improvements. The measurement range requirements are from 1 mA to more than 150 kA with frequency response extending from DC to 20 kHz and beyond. The accuracies required are often 0.1% over a temperature range from -40 ºC to +60 ºC. Several leading edge applications of the optical current sensor are presented, along with a discussion of some developing power system architectures that fully capture the advantages of this new technology. The main challenges to face are identified.
