WebOct 1, 2008 · The calculation method next requires that we determine the sum of the resistance and reactance values to the point of the fault. At that point, the total impedance per phase can be determined to the point of the fault by: With that established, we must now determine the short circuit symmetrical root mean squared amps at the fault. WebCalculate Results The relationship between A1C and eAG is described by the formula 28.7 X A1C – 46.7 = eAG.
