<p>Method for supplying current to a reactor, wherein one or more electrodes, which are fed through a wall of the reactor, of an electrical energy network which is DC--isolated from ground potential are respectively connected to an electrically conductive element so that an operating voltage is respectively applied to the at least one electrically conductive element and electrical current flows through it, wherein there is respectively a seal made of an electrically insulating material between the wall of the reactor and the electrode, wherein the electrical energy network is monitored for insulation faults and a fall below a particular insulation resistance triggers shutdown of the electrical energy supply, and wherein the switching threshold is determined by taking into account at least one parameter from the group consisting of seal geometry, seal material, supply voltage and the maximum possible electrical energy input into the seal immediately before shutdown, triggered by the maximum theoretically possible leakage current through the seal. Device for the simultaneous monitoring, sealing and electrical insulation of an electrode, characterized in that the seal contains an electrically conductive core which comprises an electrical connection facility. Electrode having an insulating seal for use in current supplies of chemical reactors, wherein the seal consists of a polymer and is shrunk onto the electrode.</p> |
