Abstract: PROBLEM TO BE SOLVED: To provide a protective method for a power cable which can surely perform quick detection without accompanying complexity. SOLUTION: A current value ik and a voltage value uk for protecting the power cable 1 are measured. All values within a measuring window are analyzed using an adaptability estimator, and they are converted into an impedance value Z. If the impedance value is not an allowable value, the power cable 1 is cut off. When an alarm signal W is issued, each window is positioned so that the starting point accords with the time of the alarm signal, and/or each measuring window is shortened.

Abstract: This high-voltage installation has a metallic enclosure (1) which is filled with insulating gas and surrounds voltage-carrying active parts. In addition, it has at least one at least partial protective coating (7, 9, 10) either on the internal surface of the enclosure (1) or on the external surface over the active parts, or at least one at least partial protective coating (7, 9, 10) both on the internal surface of the enclosure (1) and on the external surface of the active parts. It is intended to provide a high-voltage installation in which free electrons are also reliably removed from the insulating gaps and in which partial discharges generated by free particles are reduced to noncritical values of intensity. This is achieved in that the at least one protective coating (7, 9, 10) is doped with at least one fullerene which absorbs free electrons. Protective coatings which have a surface of vapor-deposited fullerene are also particularly suitable.
