How a Downed Transmission Line Can Trigger a Cascading Power Failure
“How can a single failed transmission line cause a whole power grid to shutdown?”
The electricity grid is the backbone of modern human infrastructure. However, if a single transmission line becomes faulty and goes down, then power will need to be redistributed throughout the entire system accordingly. If no care is taken, then the extra surge of electricity can overwhelm other transmission lines and cause them to fail, repeating the process until a cascading power failure occurs such as in The Northeast Blackout of 2003. This is How a Downed Transmission Line Can Trigger a Cascading Power Failure.
