Talk:Overhead line

Where should this be moved to? overhead line? overhead lines? overhead power transmission? --Robert Merkel

Comparison with streetcar/tram style lines could be interesting

I'm curious about what differences there might have been with old equipment used for streetcars. A lot of those vehicles had straight collection arms (instead of pantographs) with pulley-style wheels on the ends. Managing a transition between breaks would seem to be more difficult, and speed would seem to be an issue (although I know such systems ran at up to 100 km/h in the early 20th century in my region of the U.S.—possibly not over breaks, but certainly in between them). —User:Mulad (talk) 14:06, Sep 29, 2004 (UTC)

History

I removed this:

The use of overhead cables conducting electricity, invented by Granville T. Woods in 1888, amongst several other improvements by Woods, led to the development of electrified railways, the first of which was operated at Coney Island from 1892.

What? By 1888 Sprague's Richmond installation was already running. An amateur named John C. Henry used overhead copper cable to power his experimental car in 1884. And overhead wire was neither the first development, nor the critical one, in developing electric railways.

Woods' invention

For those curious, Woods' invention was not of the use of overhead wire for powering electric railways, but of an improved wire carriage (or "troller" or "traveller" designed to ride on top of a wire. These had previously been in use by other inventors, but Woods' invention was of an improved type with three wheels on a single wire and flanges, all apparently to address the problem that trollers had in falling off the wire. He did not submit a model, so I don't know that his design was ever tested.

The upshot is, that once sprung trolley poles were successfully deployed, all trollers became obsolete. -- Cecropia | explains it all ® 18:07, 25 Feb 2005 (UTC)

I am still new in this electrical knowledge, but somehow can someone tell me the differences between LRT and trams?

LRT and Trams.

Power Grids

please somebody help me out ....regarding what is proper functioning of power grids in india/US?

could somebody explain me about the ring main units working and about the construction of Ring main units..
