System and method for detecting a failure of high impedu00c2ncia in a system of electric energy distribuiu00c7u00e7o multi grounded circuit, and methods to generate a signal to exit the sub digital stancialmente in odd harmu00e2nicos consisting of a digital input signal.To detect the statement of an event in at least one digital signal to disable a detector of fault of high impedu00c2ncia in a system of energy distribuiu00c7u00e7o trifasico multi grounded. The system and method monitors a quantity of odd numbered harmonics within a power distribution system using a digital filter.A normal level of odd harmonics for the monitored quantity is established. By means of predetermined periods of time, the odd harmonics within the quantity of energy distribution are compared to normal level, and a determination of a failure of the high impedance is present in the power distribution system monitored is made.
