Power failures are particularly critical at sites where the environment and public safety are at risk. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation. There are many causes of power failures in an electricity network. Vehicle lights provided the only illumination during the 2009 Ecuador electricity crisis.Ī power outage (also called a powercut, a power out, a power failure, a power blackout, a power loss, or a blackout) is the loss of the electrical power network supply to an end user. For other uses, see Power Outage (disambiguation). For intentionally engineered ones, see rolling blackout.
This article is about accidental power failures.
