Episode Details

Ever driven past a fenced lot full of buzzing wires, ceramic insulators, and DANGER HIGH VOLTAGE signs? That's a distribution substation — and it's one of the most elegant solutions in electrical engineering. This episode explains why we use high-voltage transmission, how substations step power down for neighborhoods, and what every component inside that fence actually does. From transformers and bushings to circuit breakers and corona rings, we break down the physics and economics that make the modern grid possible. Plus: why we don't just put a transformer on every house.
