We have just completed a NER (neutral earthing resistor) replacement project at the state-of-the-art, 635-bed, NHS Peterborough Hospital at Bretton Gate, Peterborough.
Replacing one NER containing three HV circuit breakers housed in single cabinet, with three individual units for better resilience, this was a staged process to enable the hospital to remain operational throughout. The work included new cable and containment for each set due to the NER re-locations within the existing plantroom. DTGen also extended the existing controls logic from its original control section on the three-section NER to the separated NER locations. A new controls junction box was used to divert and extend out to each new NER. The work also involved replacing cables between each HV junction box to the alternators on all three Cummins 11kv high voltage generator sets.
Kenny Berrie, Head of Technical at DTGen, said: “As with any hospital project, the work required meticulous planning as it was only possible to work on one set at a time in order to maintain enough capacity on the standby generators to cover the hospital load in the event of a mains failure.”
“With ten of our own specialist HV engineers and longstanding relationships in the health sector, we are a trusted supplier to the NHS and pleased to be able to support these mission-critical upgrades with the knowledge and experience required to ensure safe delivery.”
DTGen has extensive experience in the health sector – during the last ten years alone, the team has delivered 190 health and NHS installations, with a total value of £22.5m. Throughout lockdown, the business also continued to support its health sector customer base including NHS Nightingale, and on-going work to design, supply and install the new standby power system for NHS Ninewells in Dundee – four prime rated 1 MVA generators to back up the hospital’s HV network.
Furthermore, on the servicing side of the business, during the last six months, DTGen has secured numerous new contracts for NHS equipment in England including the University Hospital of North Tees; Fosspark Hospital, York; Pinderfields and Pontefract Hospital; and the Northumbria Specialist Emergency Care Hospital in East Cramlington.
