What levels V(THD)are above industry standards in a substation with a capacitor bank. What level of harmonics is acceptable.
I am looking into what levels of harmonics (w/o a study) that can we valadate a need to install a hi-pass filter, in the cap bank curcuit. Im currently researching IEEE...
a substation's has a 3-step 21.6 MVAr capacitor bank where 38 kV vacuum switches are used to switch the bank in and out. When solidly grounded Y system has a line to ground BIL of 150? if you take the rms value of 38 kv = 27 kV and the BIL at 27 kV= 150. The system is 34.5 kV and the...
I have noticed that the accuracy of potential or current transformers used for metering is expressed "0.3 WXYZ". What do the letters represent? this could be on a 800:5 1600:5...etc.

In currently creating a spread sheet to size a capacitor bank at a wind farm. Because turbine is an inductive machine cap banks are used to offset the inductive influence at the collector system. The xfmr mfg's cut sheet did not provide it. I have my collector CU losses from wind plant, the CU...
