The safe, efficient and reliable distribution of electricity is critical for clients in all market sectors. It is imperative that accurate electrical design, system performance, and grid integration studies are undertaken to ensure these requirements are met.

Frazer-Nash Consultancy, can offer a variety of services to meet these requirements:

• Electrical network study capability using industry standard tools
• Load Flow and fault level studies for various operating arrangements
• Dynamic electrical system studies and transient modelling
• Protection Studies to assess the suitability of switchgear rating and the discrimination of device settings
• Grid Code evaluation and support of new generation connection proposals

These services are based on many years of experience in the power and energy sector (nuclear, conventional, oil and gas, renewables), transport and industrial applications.

Through access to many years of engineering design and analysis skills, Frazer-Nash is able to combine a practical understanding of plant and systems with leading-edge modelling techniques.  Our analytical skills allow us to predict performance in detail and evaluate the effects of design proposals and changes, enabling the effective, reliable distribution of electricity for the client.

Optimised performance is achieved by reviewing initial design concepts and then highlighting the appropriate trade-offs which are identified.  These risk areas are then used to focus analysis, thereby reducing development times and costs.
