IMPACT OF GROUND WIRES ON THE SERIES IMPEDANCE, VOLTAGE AND CURRENT CONDITIONS OF OVERHEAD POWER LINES

Ground wires are bare conductors which serve to protect the power line from the lightning strike. This article deals with the calculation of the series impedance of the 110 kV overhead power line with one ground wire. The article examines the effect of the ground wire on the series impedance of th...

The article examines the effect of the ground wire on the series impedance of the 110 kV power line compared to the same power line without the ground wire. In the next part, the principle of elimination of the ground wire is described and the method of including the influence of the ground wire on the series impedance of phase conductors of the 110 kV power line is also described.
