We have a proven track record of delivering large-scale projects within both the utility sector and private networks arena and have highlighted below some of our recent successes:

Utility Sector Contracts

We have recently secured a multi-million pound contract with ScottishPower as part of their DPCR5 asset replacement programme which runs between 2013 and 2015.

  • 33kV Primary Substation Reinforcement
  • 33/11kV Transformer Replacement
  • 11kV Switchboard Replacement

Our unique selling point is that our service delivery is completely in-house negating the requirement to subcontract services in with the exception of civil works.

Private Sector Contracts

D & A Systems have recently secured a contract at one of Europe's largest manufacturing complexes at Airbus UK in Broughton. The prestigious project worth circa £1.5 million will involve upgrading the site electrical infrastructure from 11kV up to 33kV, including construction of a new substation building and switchroom with ABB UniGear ZS1 Switchboard.

Operating under a separate contract, D&A Systems were employed to undertake the 33kV contestable connection for the project by Matrix Networks Ltd, equipping a 33kV Primary substation which was later adopted by ScottishPower following handover.

Electrical Testing & Inspection

Workplace safety is a tightly legislated area, with ever more stringent regulations requiring that all electrical equipment used in, or associated with, places of work be maintained to prevent the risk of accidents.

The main statutory regulations are: Electricity At Work Regulations 1989 (EAWR), The Provision and Use of Work Equipment Regulations 1998 (PUWER), The Health and Safety at Work Act 1974.

As an NICEIC approved contractor we will carry out periodic inspection testing on any existing installation for compliance with British Standard BS7671 (17th edition) (IEE Wiring Regulations).

Portable Appliance Testing (PAT)

D & A Systems offers a simple and cost-effective solution, enabling all companies to comply with their legal obligations. We use the latest computerised test equipment and software which will enable us to produce asset registers detailing all tests performed.

Thermography

Infrared thermal imaging is an invaluable method of locating inaccessible, hidden faults quickly and efficiently. We can provide a thermal survey of plant and systems, usually while equipment and systems are in an on-load condition.

Quality Power Management

Unexplained power cuts? Circuit breakers tripping out for no reason? Power spikes? High energy use? Today's hi-tech, power-hungry businesses depend on having a clean, consistent power supply.

Voltage fluctuations, harmonic pollution, power failures, and load imbalances are increasingly common; at worst microprocessor-based equipment can be damaged, and production lost.

D & A Systems provides a comprehensive range of services to tackle these challenges, including site monitoring surveys and detailed reports.
