High Voltage & Arc Flash Conference - Download the Conference Program

September 2025 – Pullman London St Pancras

The High Voltage & Arc Flash Conference is a must-attend event for professionals working with high voltage systems across utilities, industrial plants, oil & gas, and mining. Taking place in London in September 2025, the event will deliver practical insights, technical solutions, and valuable networking opportunities.

The conference will explore key topics including the design, installation, testing, commissioning, and maintenance of high voltage systems. It will also examine arc flash hazard management and recent updates to relevant industry standards.

Technical sessions will cover a broad range of HV equipment and components—such as substations, transformers, cables, and switchgear—while addressing challenges in system reliability, asset lifecycle management, and sustainable operations. Attendees will gain knowledge on best practices, evolving regulations, and strategic maintenance programs.

Participants will have the opportunity to hear from leading industry experts, engage directly with speakers, and discuss real-world challenges. Whether you're looking to stay current with the latest industry trends, enhance your understanding of standards, or discover new approaches to HV and arc flash safety, this conference offers a valuable platform for learning and professional development.
