A Distribution Line Model for Lightning Overvoltage Studies
IEEJ Transactions on Power and Energy, 2008 AbstractRecently, the focus of lightning protection measures for distribution lines has moved from a nearby lightning stroke to a direct lightning stroke. Studies of direct lightning stroke countermeasures are generally carried out by digital simulations using the EMTP (Electro‐Magnetic Transients Program).
