An Improved Algorithm to Monitor the Phase Difference of Three
An algorithm for monitoring phase difference of three-phase power without using currents demodulated by fiber-optic current sensor is proposed, which monitors the peak-to-peak of the three groups of
Fiber-optic current sensor
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.
FOCS – Fiber-Optic Current Sensor
The FOCS system utilizes the Faraday effect to measure current. A simple loop of optical fiber is wound around the busbar in place of the complicated and bulky sensor head of conventional transducers.
