This video looks at how electricity is distributed from the power station to consumers along the National Grid. It provides an overview of the entire distribution network, and looks at how step up and step down transformers are used to reduce line loss during transmission and make the voltage safe for use in homes. This video highlights other safety features including earth rods, insulators, and circuit breakers, giving us insight into how they play a part in larger scale systems.
