Abstract
All available model used to determine the 50% breakdown voltage for rod-type ami
conductor-type gaps subject to switching is impulse wave forms has been applied to a tower-conductor
window gap configurution. The results for rod-plane, conductor-piane and tower-conductor
window gaps have all been compared and correspond well with practical data. III
order to app(v the model, a charge simulation technique has been adopted ill conjunction
with the 'Coulomb 3D' charge simulation package. Additional tests have been performed
where parameters of'the charge simulation method am! the electrode geometl:p hare been
adjusted and consequent conclusions made. Recommendations for further application of tile
model have been suggested.
