  One of the main parameters for overhead lines designing is conductor oscillation that has a special role for determination of conductor’s gaps. One of the kinds of oscillations is galloping which creates economic losses for utilities. In this paper, a dynamic model of single conductor overhead lines that has vertical motion is investigated and according to applicable differential equations, this model is simulated for estimation of galloping amplitude. Also by using of control theories and mathematical approximation, a new electrical model is presented. Moreover by using of nonlinear control theory, system equivalent point has been determined and the amount of damper damping coefficient for decreasing of the oscillation amplitude has been evaluated.
