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
