ABSTRACT OF THE DISCLOSURE A method and an apparatus for relieving a capacitor of a controlled series compensator as a function of the load on its arrester when high-current line faults occur. The current flowing through the arrester is used to determine its absorbed energy, from which a temperature gradient is then determined as an indicator of a sudden load on the arrester and compared with a limit value. This comparison value is processed, as a function of the determined actual arrester temperature and the measured line current, to yield a control signal. The power converter valve of the controlled series compensator is triggered in response to this control signal in such a way that its equivalent impedance is switched from capacitative to inductive. The number of disconnections required as a result of high-current line faults is thereby considerably reduced, thus greatly increasing availability of the system. NY1-S:\RLM\PF01\128532-67190-923270
