    Calculating Resistance and Reactance from positive sequence fault current

    Dear All, I know following two parameters a) Maximum three phase fault current in amperes (A) and phase angle in degrees (B). I want to calculate the positive sequence resistance (R) and reactance (X) from above two variables for a symmetric system. I couldn't figure out a way to find R and X...

    11kV vs 22kV distribution voltage

    Hi, what are the possible reasons for selecting 11kV underground distribution system vs 22kV underground distribution system for urban area. I know about 22kV can carry twice the load compared to 22kV. How about impacts of pricing, fault level, stepdown from 132 kv to 22/kv etc. Thanks
