High-Voltage Engineering

High-Voltage testing

Typical consulting services provided by PhysElec Solutions in high-voltage engineering include, but are not limited to:

  • Gas discharge physics.
  • Point discharge / corona measurements, analysis and engineering (DC, AC and impulse).
  • Testing of lightning protection systems under impulse and composite (DC + impulse) voltages and electric fields.
  • Testing of surge protection devices according to national and international standards.
  • Electric field modelling using numerical techniques.
  • Insulation coordination.

PhysElec staff have decades of experience with all aspects of high-voltage engineering as it relates to lightning protection, surge protection and earthing & grounding. Examples of projects undertaken include:

  • Corona studies of lightning rods at various state-of-the-art high-voltage facilities around the world;
  • Impulse testing of air terminals at various state-of-the-art high-voltage facilities around the world;
  • Investigations into the fundamental gas discharge physics affecting corona performance of lightning rods;
  • Finite element modelling to optimise the positioning of lightning rods on buildings; and
  • Investigations of side-flashing from downconductors.
