SOME FEATURES OF TRAVELING WAVES ON CABLES

This contribution looks into the validity of some general suppositions of travelling waves on cables. It is, amongst others, generally accep ted that the load voltage during a switching transient will rise to no t more than twice the input surge voltage magnitude and that this can only be associated with relatively fast rise times. It is also general belief that the period of the oscillating load voltage is only depend ent on the cable feeding the load. These assumptions are sometimes wro ng. Simplified explanations based on basic circuit theory are given on when this could happen.
