摘要： A circuit-breaker including at least one insulating interrupting chamber inside which there are contacts and a blast nozzle. The insulating interrupting chamber is placed on an insulating support containing a drive rod. The circuit-breaker further includes a first terminal and a second terminal. The circuit-breaker has at lest one fluorescent or scintillating optical fiber disposed inside the support and constituting a symmetrical loop around the drive rod. Each end of the fiber is connected to a photodiode equipped with an amplifier. Light propagated in the interrupting chamber, as a result of arcing, reaches the optical fiber loop via a light passage within a terminal of the interrupting chamber remote from the arcing zone within the interrupting chamber.

摘要： The method is intended for use in a step-down high tension current measuring apparatus using the Faraday effect and including a Sagnac interferometer having an optical loop constituted by a fiber (47) surrounding the high tension conductor (11) conveying the alternating current to be measured and terminating at an integrated optical circuit (43) which delivers an output light beam to an electronic circuit with the optical power of the light beam having a component in its spectrum at a frequency which is a sinusoidal function of the phase difference generated by the Faraday effect, with the coefficient of proportionality being referred to as a scale factor. The method consists in periodically updating the scale factor used for interpreting measurements on the basis of D.C. components in the output signal from the interferometer which appear in response to two successive disturbances which modify the Faraday effect and which are caused by means of a test direct current taking two different successive values and applied to auxiliary coils (44, 45).
