A call-center is having some power quality problems that I am unable to diagnose. Occasionally, some of the computers will just re-boot, as if the power has been interrupted. They are not all in the same general location, nor are they all fed from the same panel. It seems to be happening more frequently in recent weeks. It does not affect all of the computers in the area, just two or three at a time. Then it might happen again in another part of the office. I have taken amperage readings of all the circuits in both panels, all three phases, and the neutrals. I have checked the terminations for tightness. I have taken temperature readings of the breakers and the neutral bar. I have found nothing out of the ordinary. The fact that more than one panel is affected and they are supplied by different transformers might indicate that the problem is coming in from the power company. But then it would affect all of the computers at the same time. Instead, it seems to occur randomly, at different times to different workstations.
I'm hoping someone here can offer me some input that may help me resolve this. Thanks.
