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:

  • Corona loss
  • Audible noise
  • Radio interference
  • Magnetic and static electric fields
  • Ionized fields, ion charges, and ion currents

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.

Typical application areas are:

  • Design of new HV transmission lines
  • Reinforcement of existing HV transmission lines
  • Converting existing AC lines to DC lines, or vice versa

Features and benefits include:

  • User friendly and intuitive GUI
  • Analyzes the fields and corona effects for AC, DC, and AC/DC hybrid transmission line
  • Evaluates the lateral profiles of the field and corona effects in a user-selectable manner
  • Calculates corona loss versus rain rates ranging from 0 to 20 mm/hr
  • Higher-order successive image method for calculating conductor surface gradients
  • Demonstrates ionized electric fields under Deutsch’s assumption
  • Allows customizability with measuring height
