    摘要： A method for estimating the insulation resistance between a terminal of a battery (Batt) and an electrical earth, comprising: -connection of a measuring circuit (CM) to one terminal of the battery (Batt), said measuring circuit comprising a resistance (R) of known value and a capacitance (CE); and -application (1) of a known input signal having an input voltage (Ue). The method further comprises: -measurement (2) of an output voltage between the earth and a point (P) located between the resistance (R) of known value and the capacitance (CE); -determination (3) of a complex impedance of a dipole consisting of the capacitance (CE) and the insulation resistance (Risol) or determination of the parameters of a differential equation; and -determination (4) of the insulation resistance (Risol) from the parameters of the differential equation or said complex impedance.

    摘要： The invention relates to a device (4) for detecting an insulation fault of a direct voltage source that can induce electrocution, comprising: first and second input terminals (-Vbat, +Vbat) for the voltage source; first and third resistive dipoles (41, 43) connected in series between an electric ground (91) and the second input terminal (+Vbat), the first resistive dipole (41) having a resistance at least ten times higher than that of the third dipole (43); a second resistive dipole (42) and a switch (45) connected in series between the first input terminal (-Vbat) and the electric ground (91); and a detection circuit (44) connected to the terminals of the third dipole (43), designed to alternately open and close said switch, measure the voltage at the terminals of the third dipole, and determine the amplitude of an insulation fault according to the measured voltages.
