An electrical grid is a network of interlocking power supply lines which carry electrical power from power generation plants and farms to customers.[1] This system is used so that the supply is somewhat decentralized. If one set of lines is damaged or overloads, the rest of the grid will ensure a reliable electrical supply to most other users.
History
At 3 o'clock in the afternoon on September 4, 1882, Thomas Edison started the first commercial power grid in lower Manhattan called "The Pearl Street Station."[2]
Technical Details
- The electrical grid is composed of over 450,000 miles of high-voltage power lines[3] and over160,000 miles of overhead transmission lines[1]
- The United States power grid is actually composed of three different grids, which are called interconnections.[3]
- Mailbox-sized monitoring devices called synchrophasers are now used to monitor the health of the grid with detail never before available[3]
