About the course

Course content

The course presents methods for accurate calculation of transients in electrical power systems. Main content:
- Summary of types of transients.
- Modelling of components (overhead lines, cables and transformers)
- Analysis of travelling wave problems. Formulation and solutions in time and frequency domain when losses and distortion is taken into account. Fourier transforms, modal analysis, and vector fitting.
- Description and analysis of ferroresonance and inrush currents in transformers.
- Lightning induced overvoltages.

Learning outcome
