Optical fiber current sensors using garnet crystal for power distribution fields

  • 45 Accesses

  • 15 Citations

Abstract

We introduce applied examples (already put to practical use) of power distribution fields of optical fiber current sensors using iron garnet crystal that have high sensitivity, high linearity and stable temperature characteristics. We also describe two types of new optical fiber current sensors developed recently aimed at cost reduction and high performance.
