Power Systems
The grid is a single machine spanning a continent, held at one frequency by second-to-second balancing. These topics animate the path power takes and what each transformation along it is buying.

The system end to end
Generation, transmission, distribution — and why they differ.
- Generating stations and their roles
- Load curves, load factor and diversity
- Per-unit system
- Single-line diagrams
Transmission lines
A conductor long enough that its own geometry matters.
- Resistance, inductance and capacitance of a line
- Short, medium and long line models
- Regulation and efficiency
- Ferranti effect and surge impedance loading
- Corona and insulators
Distribution and cables
The last few kilometres, where most of the network actually is.
- Radial and ring main distributors
- Underground cables and grading
- Substation layouts
- Earthing systems
Fault analysis
What happens in the first cycle after something goes wrong.
- Symmetrical faults and fault MVA
- Symmetrical components
- Unsymmetrical faults: LG, LL, LLG
- Circuit breakers and fuses
- Protective relaying schemes
Analysis and operation
Running the network, not just building it.
- Load flow: Gauss-Seidel and Newton-Raphson
- Economic dispatch
- Power factor correction
- Steady-state and transient stability
- Load frequency control
