Calculation of transient resistance of groundings using the finite difference time domain method

A short review of widespread methods for calculation of transient grounding characteristics and more detail review of the Finite Difference Time Domain method (FDTD) have been given in the paper. Comparison between FDTD and other methods and main features of application FDTD for transient grounding characteristics calculations have been made. An example of transient resistance calculation of metallic rod using FDTD has been represented.

Correction of errors caused by stepwise approximation of a wire in finite difference time domain method

Staircase approximation application causes an error in velocity of waves' propagation along the conductor. It has been shown that staircase approximation also causes another error which appears as a decrease of wave impedance. A possible way to reduce these errors has been proposed in the paper.
