    摘要: The capacitor of high thermal stability includes a high-voltage electrode (HT) extending in a longitudinal direction (AX), a cylindrical printed circuit (CI) coaxially surrounding said high-voltage electrode and including an electrically conductive track forming a low-voltage electrode (BT), and a frame (CH) having a cylindrical inside surface (SI) coaxially surrounding said cylindrical printed circuit (CI). The printed circuit is slit along a generatrix (G1) of the cylinder that it forms and it is rigidly fixed to the inside surface by a fixing point (F1, F2). The frame includes guide means (A1, A2) for holding said printed circuit (CI) near the inside surface (SI) whilst allowing it to expand along said inside surface of the frame. This provides a capacitor of high thermal stability and very simple construction which is suitable for carrying out measurements on a gas-insulated high-voltage electrical line.

    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).
