Abstract
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 (G) of the cylinder that it forms and it is rigidly fixed to the inside surface by a fixing point (F, F). The frame includes guide means (A, A) 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.
