The analysis and comparison of accuracy of numerical solutions received by Finite Difference Time
Domain (FDTD) method and Godunov's method at the solution of the cable equations is carried out. It is demonstrated,
that at sudden short circuits and at transition to idling mode in numerical solutions received by means of
FDTD method for long lines with the distributed parameters appear strong nonphysical oscillations. It is shown,
that the settlement scheme offered by authors on the basis of Godunov's method is deprived these lacks and provides
high accuracy for the numerical solutions received at the analysis of dynamic modes in long lines, caused
by sudden short circuits and line transitions in an idling mode.
