Resumen
Invention of a method and system for locating earth faults in alternating current in electrical systems in direct current with inverters based on the statistical calculation on the voltage measurement in a device installed between a neutral point of the system and earth that allows to calculate the phase that is missing, as well as the percentage of failure on the impedance of said phase without the need to measure currents or know impedances of the system.
