Attractive Space Evaluation Method for HVDC Transmission Lines
EnergiesHigh-voltage direct current (HVDC) transmission lines are increasing in number and overall length. This means their lightning protection must be of higher importance as well. Probability-modulated attractive space (PMAS) theory is a proven geometry-based method for lightning protection calculations.
