Introduction to Electrical Networks and the Electricity Supply Industry

Course summary

This one-day course delivers an essential understanding of the electricity distribution industry in the UK. Aimed at anyone with an interest in electrical networks or the electrical supply sector, it introduces the most common network structures, major components and the concepts behind network function and operation.

It will provide a robust foundation of the UK electricity supply sector, demystifying the terminology, key concepts and the roles and structures within the industry, without using confusing jargon.

By the end of the course delegates will have an appreciation of the dynamics of electrical networks, key technologies, engineering culture, the future challenges that face the industry today and the need for change in the future.
