Maybe a capacitive load in your facility ? Whenever I've looked at it - it's always been pretty clean. For years we used the AC mains for time keeping - but have found in some locations - especially ones with lots of dimmers - zero crossing counting was ineffective. My feeling was that dimmers that chopped the ac wave form in the middle sent out a large amount of noise over a wide spectrum.
