Course Overview

This EUSR Impressed Voltage Awareness for Designers course is specifically designed for engineers, designers, CAD technicians, and utility consultants who work on high voltage (HV) design projects near National Grid infrastructure. This EUSR-approved training equips design professionals with the knowledge to identify, assess, and mitigate impressed voltage (IV) risks during the design phase of electrical projects.

Impressed voltage can induce hazardous electrical potentials onto nearby metallic structures, posing serious safety risks during construction, commissioning, and maintenance. By attending this course, designers will understand how to integrate safe design practices, comply with National Grid standards, and actively reduce the risk of incidents associated with impressed voltage.

Delegates completing this course will be able to:

Recognise IV hazards in substations, HV layouts, and utility networks
Apply safe systems of work at the design stage to prevent impressed voltage issues
Interpret National Grid Supplier Requirements (SR/163, SR/188, SR/234) in relation to design
Enhance collaboration with construction and site teams to support safe commissioning

This course is ideal for anyone responsible for designing, reviewing, or managing electrical infrastructure projects in HV environments.

This course is designed to provide guidance and best practice for those working on or in proximity to National Grid Electricity Transmission (NGET) assets, it references NGET procedures and industry practices to support understanding and application in the workplace. It is not an official NGET training course and is not endorsed by or delivered on behalf of NGET.
