FACE (Field and Corona Effects) provides faster solutions for determining the overall corona and field effects of high voltage AC, DC, or AC/DC hybrid transmission lines, such as:
FACE calculates the audible noises and corona losses using empirical formulas developed by industry standards. It computes radio interferences with the semi-analytical method, where generating functions available in literature have been implemented as a user-selectable parameter. A frequency domain model analysis technique is utilized to rigorously examine the effects of transmission line geometrics.
The charge-free fields are calculated by the methods of successive images. Ionized fields at and above ground plane for DC, as well as AC/DC hybrid cases, are computed by implementing an algorithm for non-linear two-point initial value problems.
