Simplified single line diagram of a single-phase transfer switch to select either 'city' (utility) power or local generator power 3-phase Intelligent transfer switch. A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a ...
A generator interlock kit (or a transfer switch), eliminates the need for extension cords to power appliances. [2]Like a transfer switch, an interlock kit lets the generator energize the panel and all of its circuits (up to the load capacity of the generator); not just corded appliances.
The generators produced 12,000 volts three-phase power at 38 Hz. Two exciter turbine/generators were initially installed to provide 125 V and 250 kW of DC excitation power for the main generators, but DC power has been provided by a static system for more than 50 years. Generators and controls were designed by Charles Proteus Steinmetz.
On December 14, 2005, a catastrophic failure in the upper reservoir dam put the plant out of operation until it was rebuilt, recertified, and reopened on April 21, 2010. [10] The new upper reservoir dam, rebuilt from the ground up, is the largest roller-compacted concrete dam in North America. [11]
Low-head pumped seawater storage: Currently at very low TRL levels but in the coming decade these technologies could become part of the energy system. Dynamic tidal power : Another potentially promising type of low-head hydro power is dynamic tidal power, a novel and unapplied method to extract power from tidal movements.
A pico hydro system made by the Sustainable Vision project from Baylor University [1]. Pico hydro is a term used for hydroelectric power generation of under 5 kW. These generators have proven to be useful in small, remote communities that require only a small amount of electricity – for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes.
