Power Plants 📍

Untangling the various equipment you might see in an electrical substation.

This is a very interesting video. Substations do a lot more then just stepping down the voltage from high-voltage transmission lines. They carefully control the output voltage and frequency, bring together often multiple power lines feeding into the system, they can disconnect and connect lines for servicing and repair. In many ways, substations really are the brains of the local power grid.
