<p>A system which permits the measurement, during operation, of the arc voltage electrodes having an upper metal portion (4) cooled by circulating water. The system employs an electrical instrumentation-cable (16) attached to a piece (5) for fixing the graphite consumable portion (3) of the electrode. This cable runs along the axis of the metal portion (4) and then inside one of the water-supply pipes (11), terminating at an electronic box (14) which converts the incoming measurement signal into a light wave.</p> |
