Introduction: The scope of this project is to build and verify simulation models of lightning strikes on lineswhere the towers  have high footing resistances (applicable to steel-lattice towers at voltages of 132kV and above), and investigate the protection options to inform decisions on lightning protection approaches.

Objectives:

1)  Understand the behaviour of transmission lines under lightning strike conditions.

2)  Determine the alternative techniques to provide lightning protection on transmission lines.

3)  Create recommendations for a lightning protection policy for transmission lines.

 

This is intended to inform the further development of SHE Transmission’s lightning protection policy.

Expected Benefits: The project will be successful if it can deliver recommendations to further improve our approach to lightning protection , and more informed decisions on lightning protection options can be made.
