Protection Design, Installation, Commissioning and Maintenance

Whether you have an existing system that needs protection maintenance,  a project concept that needs Front End Engineering Design (FEED), or anything in between, EDS HV can help.

Our protection design, installation and commissioning engineers have many years’ experience within National Grid, DNOs and consultancies.  At EDS HV we have worked on schemes from large LVAC switchboards up to and including 400kV feeders and Supergrid Transformers (SGTs).  This includes, but is not limited to:

• Busbar protection
• Cable protection
• Distance protection
• Transformer differential and REF protection
• All transformer mechanical protections (Buchholz, PRD, Winding Temperature)
• Feeder/Transformer Overcurrent/earth fault
• G59/3 (ROCOF, UV, OV, Uf, Of, Vector Shift, NVD)

Our vast experience spans all of the protection applications. As well as routine maintenance, fault finding and repair, we have also designed, installed and commissioned retrofits and upgrades.

If you don't have your own documentation procedures or forms don't worry as EDS HV can provide you with the required commissioning documentation.   However, we are also comfortable to work with your documentation system.
