Summary

This paper addresses the importance of the technical knowledge required for protection teams in the electrical sector, focusing on disturbance analysis. It highlights the need for teams trained to identify and resolve faults, using standardized methods and historical data to improve system reliability. Disturbance analysis techniques are presented, including the use of oscillography, which can be analysed in time and phasor domains, allowing the identification of fault characteristics. In addition, it is discussed that statistical data helps to elucidate the possible causes that originated the disturbances.

It is emphasized that the evolution of learning in protection through perturbation analysis is interesting, due to the possibility of knowledge growth through the increasing difficulty of the perturbations.

This paper also analyses real cases with high-resistance faults, where fault location can be compromised due to the outfeed characteristic, in addition to significant disturbances resulting in stable and unstable power oscillations.

It is concluded that the continuous training of teams, combined with the efficient use of disturbance analysis methods and knowledge of disturbance data, is fundamental for the development of protection teams and for improving the reliability of the electrical system.
