11000 KV Substation Earth System: Embassy Gardens London

Client: UK Power Solutions

The project was to install an earth system compliant with BSEN 50522 and 7430 to the substation rooms of the new apartment blocks being built at Embassy gardens the systems would entailed a 40 x 4 mm Marshalling bar fix around the internal walls of the substation room, connection to the external earth system where required, and the installation of all internal connections to the metallic fixtures within the room. There were three substation rooms in different stages of construction one of which was almost ready to have the equipment brought in which meant our time frame to complete, test and sign off was short but we were able to achieve this.

Solving concerns

Testing the system was the main issue on this contract as one of the blocks was completed and had tenants living in them which restricted the amount of cable run locations for the test probes used in the fall of potential test method. Finding a clear path without interference from cables and metallic pipe work when testing the systems using the FOP method proved to be difficult but was achieved to the standard and agreed by UKPN.

Execution Substation Earth System London

The works were completed well within the agreed time and within the budget without any major upset to the public.

We were able to guide the building contractor at this point on the works up and coming works to the other substation rooms so that the installations run a little smoother, each room had a similar installation and design, and we were able to coordinate the works to each room so that the maximum amount of installation could be achieved in each visit to ease the pressure on the main contractor. As before the installation was installed, tested and confirmed by UKPN on time and in budget.
