WebGeometrical mean radius (GMR): Term in power transmission lines corresponding to the size (radius) of power lines used to determine their associated inductance and capacitance. Line Inductance The following general formula can be used for finding the inductance of each line in a transmission system. WebPutting the values of GMD and GMR L in the equation L = 2 * 10 -7 ln ( GMD/GMR L ) we obtain inductance per meter per phase In above calculation for GMR L the conductor is circular of radius r. But in actual practice ACSR conductors are mostly used, so for inductance calculation r' is replaced by D s as supplied by the manufacturer of ACSR ...
