Abstract

The paper presents a new approach to high impedance fault detection based on wavelet packet analysis. The nature and dynamics of the arc phenomenon related to high impedance faults are analyzed. A background is reported about wavelet transform and wavelet packet decomposition. Then, detecting criteria are proposed and assessing parameters calculated. Finally, in order to evaluate the procedure, the approach is applied to power system signals in normal conditions
