Abstract

Disclosed is a method for supplying current to a reactor, wherein electrode(s) of an electrical energy network (EEN), which is DC-isolated from ground potential, is/are fed through a reactor wall and connected to an electrically conductive element (ECE) so that an operating voltage is applied to the ECE and electrical current flows through it. A seal of electrically insulating material is provided between the wall and the electrode. The EEN is monitored for insulation faults. A fall below a particular insulation resistance triggers shutdown of the electrical energy supply. The switching threshold is determined by taking into account at least one of the following parameters: seal geometry, seal material, supply voltage and maximum possible electrical energy input into the seal immediately before shutdown, triggered by the maximum theoretically possible leakage current through the seal. A device and an electrode having respective seals are also disclosed.
