Damper winding. Bars and rings of the damper (amortisseur) winding of an AC generator (General Electric, early 20th century). Note the gaps in the cage along the quadrature axes. The damper winding (also amortisseur winding [1]) is a squirrel-cage -like winding on the rotor of a typical synchronous electric machine.
Originally named Allen Manufacturing Company, the business produced hexagonal set screws and wrenches to fasten them. The terms "Allen wrench" (American English) and "Allen key" (British English) [3] are derived from the Allen brand name and refer to the generic product category "hex keys". W.G. Allen [4] filed the first related patent in 1909 ...
A Stockbridge damper is a tuned mass damper used to suppress wind-induced vibrations on slender structures such as overhead power lines, [1] long cantilevered signs [2] and cable-stayed bridges. The dumbbell -shaped device consists of two masses at the ends of a short length of cable or flexible rod, which is clamped at its middle to the main ...

Newfoundland and Labrador has 74 power stations, with a generating capacity of 8,652 MW; the province mainly relies on hydropower for its generation needs. The province's largest power station, the 5,428- megawatt Churchill Falls Generating Station, annually generates over 35 TWh of electricity that is mainly sold to Hydro-Quebec, under a 65 ...
Inertia damper. An inertia damper is a device that counters vibration using the effects of inertia and other forces and motion. [1] The damper does not negate the forces but either absorbs or redirects them by other means. For example, a large and heavy suspended body may be used to absorb several short-duration large forces, and to reapply ...
She had chosen the destination because of its fresh air and fresh fruits—both in short supply in New York during the Depression—and soon they all boarded a steamship, spending several weeks ...
This is a list of electrical generating stations in Alberta, Canada.. Alberta produces a large share of its electricity through natural gas.Over the last few years, [when?] a booming economy and the deregulation of the electricity market has led to the construction of dozens of new facilities—primarily alternatives (cogeneration, waste heat recovery) and renewables (e.g. wind, solar, biomass ...
