Electrical system and method for determining a potential functional impairment in the electrical system

Abstract

An electrical system has a system housing and electrical components in the housing. At least two conductors of at least one of the electrical components are electrically insulated from one another by an electrical insulator. A sensor system is configured to detect a deposit of an electrically conductive foreign matter layer on the electrical insulator. The sensor system has a measuring surface arranged within the system housing on which at least two spaced-apart electrodes are arranged. The sensor system has a measurement circuit which is configured to measure a parameter which depends on a current flowing between the at least two electrodes. There is also described a method for determining a potential functional impairment in the electrical system.
