Current required by fiber optic sensors

Home / Current required by fiber optic sensors

The interference pattern relative to a reference waveform is an optical intensity value corresponding to the current magnitude. Utilizing a single-ended optical fiber wrapped around the current conductor, FOCS exploits the ( Interferometric fiber optic current sensors (FOCS) employ circularly polarized light traversing a closed loop path around an electrical conductor's current-generated magnetic flux, which reflects off a mirror. As FOCS are resistant to effects from magnetic or electrical field interferences, they are ideal for the measurement of electrical currents and high voltages in or other environme.
