North West Hospital - New Dual Unified Primary and Secondary Power Infrastructure
Successful Design, Project Management and Commissioning
Completed in 2021 the £2.5M comprised of:
New HV Ring Circuit
Dual low loss distribution transformers
Dual containerised standby diesel generator
ASCO Closed Transition Bypass Switches
Active Harmonic Filtration Equipment
Interconnected LV Distribution Switch Boards
Multiple Diversly Routed LV Supply Circuits to remote A and B Section Boards
Associated Civil Engineering
Factory Testing
Integrated Systems Testing
Key Features
Prior Load Monitoring and subsequent power analysis revealed spare capacity negating the need for a new primary substation
Energy Efficiency was Key - Air Source Heat Pumps were used switch room heating and Engine Block Heating along with Amorphous Core Low Loss 1600kVA Distribution Transformer having only a 630W no load loss.
Active Harmonic Filtration equipment provided anti-phase correction to the inverter rich load resulting in a reduction of harmonic load losses
A parallel Theatre refurbishment and extension project require early 'Resilient Power On' dates to be achieved
A compact area and live hospital environment posed significant challenges to the construction time and the migration of existing critical supplies to the new infrastructure.
Project Completed - Within Pre-construction Estimates and On Time - A True Credit to the Trust, Design and Construction Team
