At Premium Power, we have a staff of highly trained engineers with extensive experience in identifying and treating arc flash hazards and electrical risks in industrial and utility environments. Premium Power has worked with clients both nationally in Ireland and the UK and internationally since 2001.

An arc flash study is based on standards (IEEE 1584) of a client’s electrical network.  The purpose of the study is to identify the maximum incident energy and arc flash boundary at every point of the network. Understanding the magnitude of the hazard is a key starting point in when preparing control measures to protect workers. Our experience and expertise with arc flash studies and related works is widely recognized in the UK, Ireland and internationally and we are used across multiple industries.


Health and safety legislation in Ireland and the UK imposes numerous duties on employers and the self-employed (contractors) in relation to Arc Flash and electrical safety in general. Employers must ensure, so far as reasonably practicable, the safety, health, and welfare at work of employees and any other persons who may be affected by their undertakings (Safety, Health & Welfare at Work Act 2005 in ROI, The Health and Safety at Work Etc. Act 1974/N.I Order 1978 in UK). This general duty extends to the provision and maintenance of safe plant and systems of work, and also the provision of such information, instruction, training, and supervision as is necessary. Arc Flash and other hazards associated with electricity at work must be managed in this context.

More specifically, employers must make a suitable and adequate assessment of the risks to health and safety, and those include Arc Flash and other risks involving electricity, and to put in place the necessary preventive and protective measures (2005 Act in ROI, Safety at Work Regulations 1999/N.I. 2000 in UK).

Persons engaged in any work activity involving electricity must be competent to prevent danger (Safety, Health & Welfare at Work General Application Regs. 2007 Part 3 in ROI, Electricity at Work Regs. 1989/N.I.1991 in UK). That means, not only to have the appropriate technical knowledge but also understanding of the hazards, risks and work precautions to be observed.


We survey and model your electrical network, and calculate prospective arc energy levels. Read about the stages of an arc flash study


We recommend measures to reduce arc flash risks.


We guide you on the equipment, PPE and labelling required.


Our Arc Flash Training CPD accredited, Engineers Ireland approved. Can be provided according to your facility’s bespoke needs.

Other parts of the Arc Flash hazard analysis service include:

Advisory on Arc Flash Personal Protective Equipment (PPE)

Network Modelling– Using advanced modelling tools for electrical networks, we supply wide range of information about the client’s electrical network

Load Flow Study– The great importance of power flow or load-flow studies is in the planning the future expansion of power systems as well as in determining the best operation of existing systems.

Short Circuit Calculations– It’s important to protect personnel and equipment by calculating short-circuit currents during system upgrade and design.

Protection Coordination– allows the protection settings to be graded throughout the plant in such a way that disruption and interruption of production equipment and systems is minimised in the event of a short circuit or earth fault taking place.



"Arc flash calculations have become a standard requirement of modern electrical systems and needs to be risk assessed and mitigated against. A comprehensive study includes load flow and short circuit analysis as well as a full review of the existing protection system on site. Our studies allow for optimum investment by providing modelling of the entire power system"
