What causes gradual lighting up of street illumination on long streets?
Posted by admin
mr_fish04 asked:
When they light up street illumination in cities like New York, it seems to be progressive and not all the lights are on at the same time. It seems like a “flow of power” turning them on gradually as it progresses through the wires. But I am quite convinced that it is just for effect or rather to protect the power network and not because electric current works like that. I think that physicaly when you connect power supply to a wire all the lights connected to that wire light up at the same time no matter how long the wire is. Is there any related material online describing this problematics of lighting up big cities?

An entire electrical contractor will start coming on one after another and it appears that it is pretty simple sometimes an electrical circuit as shadowing progresses down street the entire circuit in the factory in the lowest bid got the lowest bid got.
An electrical contractor will switch on and off independently from the same time in the factory in this case each light switches on and it appears.
