System and method for locating ground faults in direct current electrical installations (1) based on the measurement of voltage or on the measurement of current, on a grounding impedance (7). This grounding impedance (7) is connected sequentially at the positive (10), negative (11) and midpoint (9) terminals of the electrical installation. From the measurements carried out, the defect is located and the severity of the detected defect is estimated. If you do not have access to the midpoint, you can connect to an artificial midpoint.
