When utility power returns for a minimum time, the transfer switch will transfer the house back to utility power and command the generator to turn off, after another specified amount of "cool down" time with no load on the generator. A transfer switch can be set up to provide power only to critical circuits or to entire electrical subpanels.

An electrical grid may have many types of generators and loads; generators must be controlled to maintain stable operation of the system. In an electric power system, automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load. Since a power ...

Scheduling and dispatch are necessary because in most electrical systems energy storage is nearly zero, so at any instant, the power into the system (produced by a generator) must equal the power out of the system (demand from consumers). Since production must so closely match demand, careful scheduling and dispatch are necessary.
These refueling Fast Fill Systems utilize an automatic shut off fuel nozzle, receiver and level control device. Refueling Fast Fill Systems operate by connection of a fill nozzle to the vehicle's fuel tank and with a source mounted pump that delivers fuel into the tank at rates up to 150 US gallons (570 L) per minute. Refueling Fast Fill ...
In data communications, an automatic switching system is a switching system in which all the operations required to execute the three phases of Information transfer transactions are automatically executed in response to signals from a user end-instrument.
