OVERVIEW
Integrated Utility Services (IUS) has an Operation and Maintenance agreement with a Packaging Manufacturing Facility in the West Midlands.
The client contacted our 24-hour HVCS emergency services team to attend site following an interruption of supplies.
Upon attendance, the IUS Senior Authorised Person (SAP) identified an 11kV cable fault immediately below the cable box of the Transformer No.3 Circuit Breaker. We implemented a safe system of work, in accordance with IUS Distribution Safety Rules and progressed the repair through to completion, testing and restoration of supplies.
DESCRIPTION
IUS received a call from a contracted customer at their manufacturing site following an interruption to their electricity supply. An SAP was immediately dispatched to respond to the customer fault. On arrival our SAP identified the fault and made the situation safe by providing the required isolations. This allowed IUS to proceeded with an investigation and found that the 11kV cable had disruptively failed below the cable box on the 11kV Circuit Breaker feeding Transformer No.3.
In consultation with the client, it was explained that a section of the 11kV cable would need replacing. This resulted in the existing 11kV cable being cut in a suitable position so the termination could be disconnected and removed. The SAP arranged for an IUS jointing and fitting team to attend site and the faulty cable was removed. A new 11kV triplex cable was installed and terminated to the cable box, and an 11kV joint was completed in accordance with IUS procedures. The cable box was filled with Guro flex as it was an old-style box, which would not provide the required clearances for an air termination.
The new 11kV cable installation was tested, and a post fault maintenance was completed on the 11kV Circuit Breaker, before restoring the supply back to normal. Liaison with our customer was vitally important, whilst the work was undertaken. This included our SAP returning to site to change over the customer supplies from a temporary generator to its normal supply.
