Abstract
In an apparatus comprising a high-voltage measuring capacitor and, in particular, comprising a high-voltage measuring capacitor formed by a high-voltage conductor of a fully insulated, metal-encapsulated high-voltage switch-gear installation and by a surface electrode associated with the former, an auxiliary capacitor is associated with and located adjacent to said high-voltage capacitor. The auxiliary capacitor is part of an evaluation device which generates a signal corresponding to capacitance changes of the auxiliary capacitor resulting from external influences. Following the evaluation device is an indicating device for signaling the occurrence of such capacitance changes and/or a control or regulating device for compensating for capacitance changes of the high-voltage measuring capacitor caused by the same external influences.
