CASE STUDY: Replacement transformer with no down-time

Over 65 years of experience going through three generations A.E Oscroft & Sons ltd contacted Rock Power Connections to upgrade their supply.


Presswork specialists – A.E. Oscroft & Sons – needed an increased supply to enable their manufacturing growth.

To eliminate manufacturing down-time, the Rock Team had a single weekend to disconnect and remove the existing 500kVA transformer; replace with a new 1000kVA model; and complete HV cabling work.

Close communication with the DNO was critical to coordinate the switch-off and on of supply to allow the transformer switch-out to occur all within one weekend.

Reece James - Operations Director - explains “Due to excellent coordination of all parties, supplies were reinstated ahead of schedule.”


* A clear schedule, agreed by all parties

* Great project management to ensure smooth delivery between civils, transport, jointing and commissioning.

* A client-focused approach to ensure zero disruption to the manufacturing capacity.
