The surge impedance is the ratio of voltage and current at any point along an infinitely long line.0Modal content
-
the load is delivered with negligible resistance when the load is at unity powerfactor0Modal content
-
impedance at which sending end voltage is equal to receiving end voltage is equal surge impedance0Modal content
-
Surge Impedance is nothing but impedance of a lossless line.0Modal content
-
surge imp is equal to the load imp then we get power factor as unity .formula is square root of L/C or AB/CD or z/y.means it matches with load imp then reduces the effect of L and C in transmission line makes the network as resistive(upf)2Modal content
-
surge impedance is depends on the per kilometer values of inductance and capacitance values and it is independent of line length0Modal content
-
In a transmission lines the reactive vars observed are equal to reactive vars generated3Modal content
