Abstract: Power Quality has been a constant topic of study, mainly because inherent problems to it can lead to great economic losses, especially in industrial processes. Among the various factors that affect power quality, those related to transients originating from capacitor bank switching in the primary distribution systems must be highlighted. In this work, the characteristics of transients resulting from the switching of utility capacitor banks are analyzed, as well as factors that influence their intensities. In addition, an espectral analysis of the voltage and current waves that reveal the harmonic components present in such a situation was made. This transients can affect the control and protection equipments as well as sensitive industrial loads. A circuit that represents a real distribution system, 13.8 kV, from CPFL (Cia Paulista de Força e Luz - a Brazilian utility) was simulated through the software ATP (Alternative Transients Program) for purposes of this study. Finally, a comparison with real-life data recorded at the distribution system was performed in order to validate the present simulation.
