Transient phenomena may be present in many devices containing components that are kept at a fixed voltage. Before steady state is reached, it may be necessary to model and understand the nature of the transients. Using ElecNet, it is possible to model and capture this phenomenon. Here, using a three dimensional, axis-symmetric model of a conductive shield, the transient aspect of the device is captured.

The quarter model used in this example consists of a spherical copper electrode with a radius of 200 mm, held at 200,000 V. The copper electrode is wrapped by a thin barrier with a low electrical conductivity (1e-14 Siemens/m). There is also, two additional cylindrical barriers placed at radii 250, 270 mm, and composed of the same material as that of the thin barrier mentioned. The sphere and all the barriers are immersed in oil with conductivity of 1e-12 Siemens/m.
