In the rare event of a lightning strike or fault on the transmission line, towers or poles may transfer high voltage and dangerous currents into the ground for a very short instant. This is known as ‘Earth Potential Rise’ (EPR). This information sheet provides information on minimising the risk from EPR.
A best practice guide on the management of trees around transmission lines.
This information sheet provides important information on Mycoplasma bovis and best practice measures in its containment.
This information sheet details Transpower's measures around biosecurity.
This factsheet provides information on the issues surrounding the growing and harvesting of forestry near transmission lines.
The Electricity Code of Practice provides minimum approach distances in and around transmission structures and conductors. These diagrams provide quick guidance and reference on minimum approach distances for 220 kV and 110 kV structures.
This guide provides information on the types of issues that development near National Grid lines can have on the lines and, conversely, the issues National Grid lines can have on development. It works through the different types of development and suggests ways of addressing the issues identified and provides some ideas on how land can be used and developed in ways that are safe and compatible with the existing National Grid lines.
This booklet provides rural landowners/occupiers with information about how to work with transmission lines on your land.
This brochure provides guidance to operating large irrigators near existing overhead high voltage transmission lines, and suggests ways to avoid electrical hazards.
