Abstract:
1. A method for supplying current to a reactor, wherein at least one electrode, which is fed through a wall of the reactor, of an electrical energy network which is DC-isolated from ground potential is connected to at least one electrically conductive element so that an operating voltage is applied to the at least one electrically conductive element and electrical current flows therethrough, wherein there is respectively a seal made of an electrically insulating material between the wall of the reactor and the at least one electrode, wherein the electrical energy network is monitored for insulation faults and a fall below a particular insulation resistance of the seal between the at least one electrode and the wall triggers shutdown of an electrical energy supply, and wherein a switching threshold for shutdown of the electrical energy supply is determined by taking into account at least one parameter selected from the group consisting of seal geometry, seal material, supply voltage and a maximum possible electrical energy input into the seal immediately before shutdown, triggered by a maximum possible leakage current through the seal.
