摘要
The lightning performance of 63 kV and 90 kV shielded and unshielded lines, protected by line surge arresters are considered. A specialized software package is used for the computation of the line fast front transients. A Monte Carlo statistical method, together with a three-dimensional electrogeometric model is used to determine the lightning stroke locations. Different arrester installation configurations are analyzed and compared. The energy duties of the line surge arresters are computed statistically.
