Innovative process to top-up transformers eliminating technical and safety risks, through the re-design of the top-up tanks and associated pumping/ injection system.

The current process involves filling new oil through the conservator which can cause dirt and debris to be flushed into the main transformer. The new system will inject oil through the cooling bank return pipe situated at ground level. At present, top-ups involve working at height, which will be eliminated with this method. Cost savings will accrue with reduction in working at height and less site staff involvement. In additon there will be the potential for automatic/on-load top-ups

This project addresses a safety Issue, working at height , once National Grid Oil Management Units (OMU). have the new top up tanks commissioned and approved then all top ups will be carried out from ground level. This will also lead on to cost savings as the requirement for a mobile work elevated platform is eliminated along with the operator.
