Arc Flash Studies in Melbourne for Safer Electrical Operations

Arc flash is a critical risk within low and high voltage electrical systems, particularly across industrial switchboards, MCCs, and distribution networks. Under fault conditions, an arc event can release extreme temperatures, pressure waves, and expelled conductive material within milliseconds, posing serious risk to personnel working on or near live equipment.

Energy Safe Victoria (ESV) requires duty holders to identify electrical hazards, assess arc flash risk, and implement controls aligned with standards such as AS/NZS 4836 and recognised methodologies including IEEE 1584.

At ARA Electrical Services, arc flash studies are carried out to provide a clear understanding of where risk sits within your installation. The focus is on delivering accurate, site-based data that can be used to improve switching practices, isolation procedures, maintenance planning, PPE selection, and overall system safety..

What an Arc Flash Study Is Meant to Show

An arc flash study is a structured engineering assessment of how severe an arc flash event could be at different points in an electrical system. In practice, that means reviewing the network configuration, fault levels, protective devices, operating modes, and likely working conditions to estimate incident energy and identify higher-risk locations. Energy Safe Victoria points to IEEE 1584-2018 as a recognised guide for performing arc-flash hazard calculations, which underlines the need for proper data and a technically sound methodology.

For industrial sites, this type of study matters because risk is rarely uniform across the system. Some boards or switching points may present significantly greater exposure than others depending on available fault current, clearing times, and how the equipment is used day to day. A detailed study helps separate assumed risk from actual risk, which is essential when planning controls and prioritising upgrades.

Why Arc Flash Studies Matter to Your Site

Arc flash studies support safer operations for electrical teams and isolations by helping businesses identify where workers may be exposed and what controls are likely to be most effective. The hierarchy of control remains central to this. Energy Safe Victoria’s guidance emphasises eliminating exposure to arc flash hazards by working on de-energised and isolated equipment wherever possible, before considering substitution, engineering controls, administrative controls, or PPE.

For a site operator, the value of the study goes beyond hazard awareness. It can influence maintenance procedures, switching methods, isolation planning, equipment selection, and staff training. It can also highlight where a board configuration, protection setting, or ageing asset is increasing operational risk unnecessarily. In that sense, a properly completed arc flash study is not just a compliance exercise; it is a practical tool for safer and more reliable system management.

ARA’s Approach to Arc Flash Assessment

ARA Electrical Services engineering team completes arc flash studies based on actual site conditions. This includes reviewing available documentation and verifying key information on site where required, including:

  • Single line diagrams
  • Transformer and supply data
  • Switchboard configuration
  • Protection devices and settings
  • Cable lengths and installation details
  • Available fault levels
  • Operating conditions of the site

Where information is missing or outdated, this is addressed before modelling to ensure results are accurate. Often extensive site work can be required to find missing information or confirm old drawing mark ups as incorrect input information can drastically change the final result.

The system is then analysed to determine fault levels, protection response, and incident energy across the installation. This allows identification of higher-risk equipment and areas where improvements can be made

Recommendations are practical and aligned with how the site operates. This may include changes to protection settings, switching procedures, labelling, or system design where required to reduce exposure.
