Abstract
A device for detecting an insulation fault of a direct voltage source that can induce electrocution, including: first and second input terminals for the voltage source; first and third resistive dipoles connected in series between an electric ground and the second input terminal, the first resistive dipole having a resistance at least ten times higher than that of the third dipole; a second resistive dipole and a switch connected in series between the first input terminal and the electric ground; and a detection circuit connected to the terminals of the third dipole, configured to alternately open and close the switch, measure the voltage at the terminals of the third dipole, and determine the amplitude of an insulation fault according to the measured voltages.
