    Capacitor Switching Transients Calculation

    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...

    Capacitor Placement in Distribution System

    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...

    Transformer impedance calculation

    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?
