Supply and installation of earth grid for new upgraded transformer including:
- 120mm2 bare c/u grading ring
- 120mm2 green/yellow insulated connections
- 4 x 5m-deep earth electrodes
Earthing Solutions used a concrete saw to cut along the existing service location to install the earth grid in the existing concrete structure. We undertook current injection testing and prepared a detailed report prior to the new transformer being energised.
The work was carried out in the vicinity of an existing live substation requiring additional care to ensure on site safety.
The project was successfully completed to the design requirements and the step-touch potential recommendations.
