CURRENT MEASURING EQUIPMENT BASED ON OPTICAL FIBER FOR MEASURING THE CURRENT CIRCULATING THROUGH A CONDUCTOR AND THE ASSOCIATED METHOD

摘要

The invention relates to a current measuring equipment based on optical fiber for measuring the current circulating through a conductor, comprising an interrogator (2) with an emitter (3) and a receiver (4), and a sensing portion (5) close to the conductor (7), the interrogator (2) and the sensing portion (5) being suitable for being connected through at least one standard single-mode intermediate fiber (6). The emitter of the interrogator (2) is suitable for emitting sets of at least two polarized light pulses to the sensing portion (5), said pulses being polarized with a specific degree difference, and the receiver (4) is suitable for determining the current circulating through the conductor (7) depending on the pulses it receives in return from the sensing portion (5). The invention also relates to a method for measuring the current circulating through a conductor with current measuring equipment based on optical fiber.
