Overvoltages Caused by Indirect Lightning Strokes
2007This chapter describes the conventional basic impulse insulation level (BIL) as the insulation strength under lightning impulse voltages. A lightning stroke is defined as a direct stroke if it hits either the tower or the shield wire or the phase conductor.

Lightning Overvoltage of UHVDC Transmission System
2017The UHVDC transmission line has characteristics of long line, high tower, and high operating voltage of the conductors, being not beneficial to the lightning protection. This chapter discusses the main differences in lightning protection of AC and DC lines and characteristics of lightning withstand performance for UHVDC lines.
