Oklahoma Road Trip: Substations

  • Aired: 01/16/2017

  • Rating: NR
You may have seen electrical substations around where you live. They are a critical part of the electrical grid that gets power from the plant to our homes. Their basic function is to step down (or up) the voltage on the wire so that we can use it. They do that by using transformers. We’ll find out how they work; and about the concepts of voltage, current, and electromagnetic induction.
