AB  - This study studies the direction of fault current
flow in power systems with the High Impedance
Grounding method (HRG). The direction of the current
was validated by two methods, the first was to process the
signals over time, applying the Fourier transformation to
determine the magnitude and phase of each of the signals.
The second method analyzes the system in symmetrical
components, determining the equations of voltages and
currents. The two methods are represented in data
diagrams to analyze and compare the results in detail.
Finally, it clarifies the confusion that exists in the
literature about the direction of the fault current, the
appropriate interpretation mode can better adjust the
parameters of the programming of the direction of the
current. In addition, a way of graphing the limits is
proposed to allow a real representation of the currents of
the electrical system.
