In your case then, you may need to pay attention to transients in your
cabling plant. Everytime a large motor starts, revs or stops, those
transients are hitting your cabling. My recollection is that you have
machine tools in addition to electronics and climate control. Even more so
then. Also grounding for your electrical system has to be proven
over-adequate. And any possible ground-loops need to be found and
remediated.
