a 100HP motor, is about 75kW, so that's a little over 200kW for 3 of them,  they might see a little blip.. especially near a 'larger' area

I work in HPC, we deal with dozens of mW. I actually did get calls for restarting "something"  being told...  please don't do that like that ...

(me and my team, unknowingly, caused brown outs *lol*)

About a mile away is a few Cinci high speed 3 spindle 5 axis gantries. Each
spindle has a 100 horse motor. I can imagine the power company could
monitor and tell when they start.

It certainly was not vibrating to that level when I was
working on it.  It did have those insane
Gettys motors and drives, so I'll bet when something was not
set up right, it could create a
lot of vibration.  With all the massive aerospace
manufacturing in the area, I can't imagine
how anybody could localize where a vibration came from, though.
