This is the fifteenth e-lesson in the Design of distribution transformers course, conducted on the Master's level. Here you can save your seat.
This transformers academy lesson focuses on leakage inductance, a key feature affecting power factor, voltage, and fault currents in distribution transformers. Leakage inductance depends on the transformer's geometry. The lesson reviews the inductance concept, explaining how changing magnetic fields induce electromotive forces. Leakage inductance arises from imperfect winding coupling, causing voltage changes under load, but can also limit current flow. The lesson introduces smart transformers - high-frequency transformers used in smart grids to convert renewable energy. The smart transformer market is growing rapidly. The next lesson will cover design examples of traditional and smart transformers. Calculating leakage inductance involves complex geometric formulas. Minimizing inductance discrepancies is crucial for power converter controllability and efficiency. The future may involve amorphous cores and solid-state components for smart grids.
