Study on the Effective Lightning Protection Schemes for Distribution Line

Since distribution lines have relatively weak insulation compared to power transmission lines, it is more liable to lightning damages. This paper reports a study of how overhead ground wire height and impulse ground resistance affect the lightning protection performance. The results obtained in this paper show that high overhead ground wire worsen the lightning protection performance while reducing the impulse ground resistance improves the lightning protection performance. Therefore, it is recommended to set the overhead ground wire lower and take necessary measures to reduce impulse ground resistance. The results obtained also confirm the crucial role of the overhead ground wire as a protection of distribution lines.

The Relationship

Adopting covered conductors and compact configuration has become the tendency in the renovation of distribution network in China. Advantages of compact configuration are discussed in this paper, which can further save the passage of distribution line, and can easily realize multiple lines in a pole. The movement process of phase conductors is analyzed by the Chord Forced Equation of the mechanical theory to obtain the relationship between the phase spacing of triangle spacer and the span between two neighboring spacers. The suitable phase spacing and spacer span are presented for polymeric and composite spacers. The superiority of compact configuration against lightning protection comparing with traditional distribution lines was analyzed.
