Hospitals and Universities

The power supply to our care and academic establishments throughout the UK is of vital importance.

The need to have a reliable energy network with appropriate resilience, including back up generation, can be lifesaving.

IUS are very experienced in meeting the exacting standards.

There are numerous essential supplies associated with hospitals and universities including laboratories, lecture theatres, student accommodation, administrative buildings, social facilities and sporting and leisure establishments.

These facilities need the services of a reliable High Voltage contractor who can respond to new connections on campus, as well as inspection and maintenance of existing assets. This can also include refurbishment and upgrade works.

All within an environment where reliability and dependability, which IUS provide, are vital.

 

IUS has carried out extensive works for hospitals and universities and we have a reputation for delivering a quality project, to budget and on time.

Safety, training, competence and experience are all needed when working in the health and education sectors.

IUS site delivery teams are appropriately certified and we have an outstanding health & safety performance.

Client

Geoffrey Robinson Ltd

Project

Day Treatment Centre

Location

Newcastle Upon Tyne

SERVICES PROVIDED
  • HV and LV design
  • Supply and installation of HV apparatus and cabling
  • Supply and installation of LV cabling
  • Supply and installation of HV/LV earth nests
  • Supply and installation of electrical protection system
  • Testing and commissioning
OVERVIEW

Robertson CE Ltd has constructed a new building at the Freeman Hospital site, now named the Day Treatment Centre. IUS's scope of works included the design, procurement, and installation of two air-cooled 11000/433V transformers with close coupled 11kV ring main units within a new substation constructed for the Day Treatment Centre. 11kV cables were supplied and Installed from an existing substation within the hospital to the Day Treatment Centre substation along with LV cables from the substation to the adjacent LV switch rooms.

DESCRIPTION

Initial design works were completed by IUS, which included a high voltage fault level and load flow study along with a protection and grading study. An earthing study was also completed for the new substation.

Two Schneider 11000/433V air-cooled transformers c/w close coupled HV ring main unit and LV cable box were supplied and installed within the new substation. An HV/LV earth nest was installed adjacent to the substation as per the design. An Intertrip relay control unit and associated cabling were supplied and installed within the new substation for each transformer for the electrical protection of the transformers.

Two 11kV cable circuits were supplied and installed from an existing substation integral to the main hospital building to the new substation. This consisted of cable fixed to containment within the hospital and external cable laid within an open cable trench excavated by others, at a length of 300m. LV cables were supplied and installed internally within the new substation from the two transformers to the two LV switchboards, with cable terminations at each end.

11kV cables were terminated at the new substation via the 11kV ring main units. The configuration resulted in the new substation being looped into the existing 11kV ring. The system was tested and energised by the IUS SAP.

Project

11kV Infrastructure for a 5MWe Solar Farm

Location

Castle Road, Cottingham, Hull

SERVICES PROVIDED
  • HV network design
  • P28 / G99 reports
  • G99 protection design
  • Earth design and report
  • Civils construction designs
  • Ground survey reports
  • Installation of 11kV infrastructure (cable installation and civils, transformers, and switchgear)
  • Test and commissioning
OVERVIEW

IUS were contracted by Hull University Teaching Hospitals NHS Trust to install the 11kV Infrastructure for a new 5MWe Solar Farm on land adjacent to Castle Hill Hospital, as part of the trusts plans to become carbon neutral by 2030.

DESCRIPTION

IUS provided expert support for the scheme, by designing the HV network, P28/G99 studies and reports, G99 protection study, earthing report, ground surveys & borehole analysis, heat gain calculations, construction designs and all other relevant design requirements. IUS constructed two substations inclusive of HV compounds, LV plant rooms and inverter rooms. The cable/duct installation carried out by IUS, involved excavation by conventional open cut trench, as well as horizontal directional drilling method.

IUS supplied and installed:
1x 2MVA transformer, 1x 3MVA transformer, 2x 11kV ring main units, 2x battery tripping units and relay panels. The IUS scope of service included an in depth and technical G99 protection scheme, installed in compliance with the local Distribution Network Operator, Northern Powergrid specification.

IUS provided a dedicated project team to ensure the day-to-day running of the project was carried out safely, efficiently and to a high quality standard, to the client’s satisfaction. IUS also provided our ‘in-house’ senior authorised person and technical service support throughout the project to ensure safe systems of work were implemented and maintained and equipment/protection was pre-commissioned to the highest of standards.
