This section gives advice on applying the right technical standards, latest news and updates to ensure you’re fully equipped to understand the complexities when installing these systems.
Standards set the benchmarks for good practice, professionalism and help provide assurance to clients and ensure their expectations are met. They also promote a culture that encourages the delivery of high quality services.
Applying the right standards is crucial when carrying out different areas of work; importantly they fulfil obligations under contract but ultimately obligations under Health and Safety and the Electricity at Work Regulations.
When designing, installing, commissioning, testing, inspecting or maintaining high voltage electrical systems, depending on the scope of work, a combination of the most recent edition of the following Regulations, standards and guidance would apply:
BS 7671 Requirements for Electrical Installations. (The IET Wiring Regulations)
BS 6626 Maintenance of electrical switchgear and controlgear for voltages above 1 kV and up to and including 36 kV. Code of practice
BS EN 50110-1 Operation of electrical installations. General requirements
BS EN 60076-1: 2011 Power Transformers
