This document summarises the issues and proposes a research work programme consisting of a series of tasks to address the questions raised. The tasks will involve detailed computations and some experimental tests with the aim to assist National Grid in developing simple and straightforward guidance relating to NSI 4 working practices.

The key objective of this project is to establish working practice requirements based on the application of innovative modelling techniques developed by Cardiff University.

  1. Production of a Induced Voltages and Currents progress report

  2. Production of a Safety Assessment progress report

  3. Production of a final report on Induced Currents and Voltages and safety practices on OHL transmission lines.
