Scotty,
Thanks for the reply. I thought that PF could be no greater than 1.0 but wasn't totally sure. The readings were taken by others and I wasn't present. I'll have to see how the readings were taken.
We've recently installed 3 100T Turbocor compreesors as a retrofit to one of our chilled water system. The manufacturer insisted that we install Harmonic Filters just upstream of the units. Checking power quality and power factors, we found that the PF before the filters was 0.8 which seems...
