Current measurement equipment based on optical fiber to measure the current flowing through a conductor and associated method

摘要

Current measurement equipment based on optical fiber to measure the current flowing through a conductor, comprising - an interrogator (2) with an emitter (3) and a receiver (4), and - a sensor part (5) close to the conductor (7), the interrogator (2) and the sensor part (5) being configured to be connected through at least one standard single-mode intermediate fiber (6), characterized in that - the emitter (3) of the interrogator (2) is configured to emit sets of at least two pulses of polarized light to the sensor part (5), said pulses being polarized with a certain degree difference, and - the receiver (4) is adapted to determine the current flowing through the conductor (7). ) depending on the pulses it receives back from the sensor part (5).
