The analysis presented relates the transient voltage rate of change to the power main (PM) line attenuation and dispersion (mainly dielectric) characteristics. The initial discontinuity produced by a load connection or disconnection is modified on propagation along the PM line. Attention is confined to differential-mode transients. The response of the line to an ideal step is analyzed to derive limits for the rate of change of the wavefront. The approximate 10 to 90% rise time is derived and FFT computations have been performed for confirmation, as a function of distance along the line from the excitation point. Attention is confined to the incident wave.

Abstract
The analysis presented relates the transient voltage rate of change to the power main (PM) line attenuation and dispersion (mainly dielectric) characteristics. The initial discontinuity produced by a load connection or disconnection is modified on propagation along the PM line. Attention is confined to differential-mode transients. The response of the line to an ideal step is analyzed to derive limits for the rate of change of the wavefront. The approximate 10 to 90% rise time is derived and FFT computations have been performed for confirmation, as a function of distance along the line from the excitation point. Attention is confined to the incident wave.
