Abstract
A method and an electrical circuit arrangement is for determining an insulation resistance of an ungrounded power supply system, which feeds electrical energy to the water-electrolysis installation. The fundamental idea of the method is based on predicting the insulation resistance of the ungrounded power supply system during an initial booting of the water-electrolysis installation and thus keeping the delay caused by the demineralization process as short as possible until the electrolysis process for subsequent booting processes of the electrolysis installation has been actually cleared. In a variation of the method, the electric conductance value and the temperature of the process water are additionally provided and recorded depending on the specific installation by the demineralization installation during the demineralization process. The result is a cost-efficient monitoring approach with a simple option for retrofitting for determining the insulation resistance of the ungrounded power supply system for the supply of water-electrolysis installations.
