Abstract

This study addresses the simulation of transient phenomena associated with partial discharges in electrical power systems, aiming to understand their behavior under transient conditions and their influence on the integrity of transmission systems. The study considers a representative 138 kV network, using distributed line models and lumped parameters, where the conductor configuration is defined as the geometric arrangement and form of electrical interconnection between phases. The results show wavefronts with rise times close to 0.5 ms and significant transient amplitudes, consistent with real-world events. The proposed solution involves the use of detailed modeling to identify critical propagation paths and assess the severity of the phenomenon. The study's significance lies in demonstrating that ATP (Automatic Phase Transformation) allows for the accurate reproduction of rapid phenomena, optimizing the diagnosis of transient behavior and supporting technical decisions aimed at improving operational reliability and extending the lifespan of the electrical system.

Keywords: Transient propagation, computational modeling, electrical insulation, transient phenomena, partial discharges.
