I have a project where LED's are installed in a building facade in SF.
My 12,000 LED's are supplied with 2.5 V + and the building, or parts thereof are my ground.
Since this installation extends to a height of 170 feet, I was wondering what sort of ground for my negative pole I could expect.
My power supply vendor brought up the possibility, that I would have my negative pole of the supply riding on incredibly dirty ground, polluted with induced AC and spikes of unknown shape.
IF so, what would be a good approach to make this work anyways?
