• Voltage and frequency stability
• Load behaviour of networks
• Effect of harmonics

Electrical machines

• Inrush current from transformers and machines
• Transformation ratio of transformers
• Efficiency of machines

Power electronics

• Rectifier
• DC/DC converter
• DC/AC converter
• Frequency converter
• Filter
