A method and a system are provided for fixing a Faraday optical current sensor in a suitable measurement position for measuring the current in a 3-phase cable that includes 3 individual section-shaped phase conductors insulated in relation to one another and encapsulated inside an insulator. The method includes providing a Faraday optical current sensor arrangement having 3 Faraday optical current sensors, each of which is fixed in a specific position outside the insulator; and providing a processing unit for calculating a current value from a magnetic field value. The method is performed by measuring 3 magnetic field values using each of the 3 sensors and calculating the current in each of the section-shaped phase conductors using the processing unit and the 3 magnetic field values.
