90MVA Transformer Relocation Between Winchester and Amesbury

Client:
KUS Engineering

Amesbury, Wiltshire

Scope of work

This 132/33kV transformer was previously located at Winchester Grid as a spare transformer for the DNO, it is now ready for service in Amesbury after a full four week project, which included the following works:

Undertaking various site meetings to discuss the commissioning, strip down, removal, transport, installation & commissioning at both locations.
A full pre-relocation commissioning checks to determine the condition of the transformer which included the correct operation of all protection devices.
We then undertook a full strip down of the transformer and cooler bank at Winchester to meet the requirements to travel on a UK road.
Our specialist contractor then skidded the 90MVA transformer from it’s storage area position at Winchester onto the semi-low loader ready for transporting to it’s new home at Amesbury Grid Substation.

Once the transformer arrived it was skidded onto the new plinth within the day and sat on new anti-vibration pads.

Modifications were required at Amesbury for the new transformer to suit the new site which included the re-handing of the cooler bank onto the opposite side.

Once the build of the transformer was complete, we then refilled the transformer with the previously removal oil and undertook the oil filtration.
Completed with a full range of commissioning as per the DNO’s specification, again checking the all protection devices was operating correctly and handover of the transformer with all paper work.
