I am plannig to install a capacitor Bank at 69/12.47 kV substation. The bank is 2700 kVAR three stage bank with 900 kVAR in each stages. I am wondering how you estimate the voltage transients due to 900 kVAR capacitor switching? Substation transformer: 14/20 MVA, Impedance, 9% Source...

TinFoil, you are right. Must of these feeders are less than 5 miles in length and feeds industrial and commercial loads with low power factors. We have already started to panalyzing them. The urgency of correcting power factors is our power purchaching contract with our power supplier. we are...

I have been working for capacitor placemnet in our 12.47 kV distribution system for power factor correction. 3 substations that are feeding from a 115 kV radial transmission line have really power factor. Each substation have kVAR demand around 5000 kVAR. To correct substation power factor to...

Thanks WBD, I was looking Electric Utility distribution.

I was looking for a good Electrical Distribution System Reference/Hand book. Could you please suggest me the nice one? Thanks

How do i calculate X and R for a power transformer like 10 or 20 MVA if i have only Z. Is there any standard X/R ratios for these transformers?
