How do emergency power systems work?
Emergency power systems can rely on generators, deep-cycle batteries, flywheel energy storage or fuel cells. Emergency power systems were used as early as World War II on naval ships. In combat, a ship may lose the function of its boilers, which power the steam turbines for the ship's generator.
When were emergency power systems used?
Emergency power systems were used as early as World War II on naval ships. In combat, a ship may lose the function of its boilers, which power the steam turbines for the ship's generator. In such a case, one or more diesel engines are used to drive back-up generators.
Can a building use emergency power?
Some buildings may even use emergency power as part of normal operations, such as a theater using it to power show equipment in accordance with the principle of "the show must go on". The use of emergency power systems in aviation can be either in the aircraft or on the ground.
What equipment is on emergency power?
Exit signs, fire alarm systems (that are not on back up batteries) and the electric motor pumps for the fire sprinklers are almost always on emergency power. Other equipment on emergency power may include smoke isolation dampers, smoke evacuation fans, elevators, handicap doors and outlets in service areas.
