Good point on the light bulbs, TJ. They were probably replacing them right and left without having any idea it was because of the surges.

Full consequences is right, Rob.  What other equipment was taking a hit from the daily spike?  I wonder if they replaced lightbulbs much more frequently than normal.

This is a perfect example of the effect of changing one thing and having that change reverberate through the whole system. Whoever set up the capacitor bank had no idea of the full consequences.
