METHOD FOR UPDATING THE SCALE FACTOR OF AN APPARATUS FOR MEASURING THE INTENSITY OF AN ALTERNATIVE ELECTRIC CURRENT BY FARADAY EFFECT

摘要

P THIS METHOD IS INTENDED TO BE IMPLEMENTED WITH A FARADAY HIGH VOLTAGE MEASURING REDUCER COMPRISING A SAGNAC INTERFEROMETER HAVING AN OPTICAL LOOP FORMED OF A FIBER 47 AMOUNT TO THE POTENTIAL TO SURROUND THE CONDUCTOR 11 PERCEIVED BY THE ALTERNATIVE CURRENT TO MEASURING AND CONDUCTING ON AN INTEGRATED OPTICAL CIRCUIT 43 DELIVERING TO A ELECTRONIC PLATINUM 46 A LIGHT OUTPUT BEAM WHOSE OPTICAL POWER HAS A COMPONENT OF ITS FREQUENCY SPECTRUM WHICH IS A SINUSOIDAL FUNCTION OF THE PHASE GAP GENERATED BY THE FARADAY EFFECT IN THE REPORT OF A FACTOR OF SCALE. IT CONSISTS OF A PERIODIC UPDATE OF THIS SCALING FACTOR FROM CONTINUOUS COMPONENTS OF THE INTERFEROMETER OUTPUT SIGNAL IN RESPONSE TO TWO SUCCESSIVE DISTURBANCES THAT MODIFY THE FARADAY EFFECT AND THAT ARE CAUSED BY USING A CONTINUOUS TEST CURRENT HAVING TWO SELECTIVE SUCCESSIVE VALUES AND PERCOURING AUXILIARY WINDINGS 44, 45. / P
