1. An electrical system, comprising:
a system housing;
electrical components disposed in said system housing;
an electrical insulator disposed to electrically insulate at least two conductors of at least one of said electrical components from one another;
a sensor system configured to detect a deposit of an electrically conductive impurity layer on said electrical insulator, said sensor system having a measuring surface arranged inside said system housing and at least two electrodes spaced apart from one another on said measuring surface; and
a measuring circuit of said sensor system configured to measure a parameter which depends on a current flowing between said at least two electrodes.
