Abstract :
This article reports measurements carried out at Lactec high voltage laboratory. It also shows how to use Steinmetz Circuit Theory to obtain computed results very similar to measured values. The article also comments how difficult it is to obtain the same results using Shelkunoff Transfer Impedance Theory. The article also recalls basic principles of cable shielding technique.
