   Hi, usually the PFcorrection is being done on a HV to MV substation, and   
   of course on the MV side.I suppose  PF can be easily measured with   
   potential and current transformers? I have a couple of slides,   
   too.(Showing those capacitor banks). I saw them on a local substation,   
   150 to 20 kV, I have also a video from the computers running the cretan   
   grid (Crete, Greece) and they know always the reactive power on each   
   city, also major substation. unfortunately the video is in greek.HTH,   
   HAND, Dimitris Tzortzakakis, ee major.
