Resumen
System and method of locating the branch with earth fault in direct current electrical systems with several branches in parallel, by measuring the current of each parallel branch of the direct current system, and by calculating the relative variation of current of each branch by switching a grounding element from an energized point of the DC system intermittently. The fault branch is located as the branch that has the greatest relative variation in current between the open and closed positions of the switching element that allows or does not allow the fault current to return.
