Archived Projects

Willesden 275kV Substation - Emergency Replacement Quad Booster. National Grid identified the need to relocate a Quad Booster from Ocker Hill substation to Willesden substation. The work involved reviewing the existing circuit and interface drawings associated with the quad boosters at both Ocker Hill and Willesden for protection compatibility and to provide drawings highlighting to show the required site modifications. All were provided on target to meet short turnaround requirements. Stocksbridge 400kV Substations - Decommissioning of Supergrid Transformers. Update of the existing, site drawings associated with the decommissioning of SGT1 and SGT2. Providing red/green drawings associated with the disposal of National Grid protection and control equipment/assets located within the 400kV and 66kV substation relay rooms. Barking Grid 400kV Substation - Network Rail Connection. Full circuit design and interface engineering associated with Barking Grid/Essex Road cable diversion and the re-connection of the T4B circuit. The provision of primary plant design engineers, and panel manufacture was also included in our scope of works. Existing drawings updated in line with current NG policies for the change of feeder protection and replacement of 25kV disconnector. Bramford 400kV GIS - 10 Bays of 400kV GIS. Secondary systems design works for Bramford GIS 400kV. Also included were circuit diagrams for the 400kV GIS local control cubicles, and interface engineering for the overall substation.
