Programme

Day one - 19 November 2024

08:50 Welcome/icebreaker
09:00 Protection Against Electric Shock
Sarah Dale , Technical Principal - Traction Power, Mott Macdonald
10:00 Case study 1 - Multiconductor modelling to assure the safety and reliability of HS2.

Overview of the application of integrated multiconductor simulation to demonstrate E&B and EMC compliance of an electrified railway. It will be shown how models incorporating the traction return circuit and common earth system, longitudinal civils assets, and command and control systems cables can be used to verify the system will comply with touch voltage and induced voltage limits.

Ian Flintoft, Principal Engineer - Electrical Systems Practice, AtkinsRéalis
