Opto-Magnetostrictive Current Measurement Instrument for High Voltage Environments

摘要

The authors present the development of a opto-magnetostrictive current monitoring device intended to be used in situations where high voltages are involved. The system offers not only measurement reliability, but to be also practical and light weighted. Fiber Bragg gratings (FBG) are employed in the measurement procedure: the current is acquired using a hybrid sensor head set-up, that is, an FBG together with a magnetostrictive rod.
