This lecture covers the calculation of short-circuit currents in electrical networks, focusing on different types of phase configurations and symmetrical components. It explains the direct, inverse, and zero sequence equivalent models of components, as well as the coupling of windings and magnetic circuit configuration in transformers. The lecture also delves into the breakdown of asymmetrical three-phase systems into symmetrical subsystems and the definition of zero sequence networks. Various hypotheses and comments are discussed, such as the consideration of permanent and symmetrical sinusoidal networks. The application of equivalent diagrams and the determination of nodal impedances are also explored.
