Abstract
The invention relates to an electrical system comprising: —terminals (V+, V−) capable of being connected to an installed electrical power source () capable of delivering an electrical voltage between said terminals; —a circuit for detecting an electrical insulation fault between the electrical power source and a housing () forming a floating electrical ground. The detection circuit comprises: •a controllable voltage generator () capable of polarizing the housing and the single first terminal at different potentials; •a current measurement device () measuring current entering on said first terminal and leaving at a point of the source; •a control unit () capable of calculating a value of at least one insulation resistance from said at least one measured current value.
