how to calculate SLG X/R from utility info?

Discussion in 'System Modeling and Calculations' started by tasamy, May 3, 2010.

    I got utility information in the form of X0/R0 and X1/R1. What formula should I use for 3phase X/R calculation? I got the SLG X/R formula as [2(X1/R1) + X0/R0]/ 3.

    Anyone? :confused:

    The utility 3 phase X/R ratio is X1/Xo
