What causes gradual lighting up of street illumination on long streets?
Thursday, October 1st, 2009mr_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?
