Arc Flash Hazard Analysis

GPA have provided arc flash assessments across the mining, oil and gas, power and water industries. Servicing greenfield and brownfield projects, including oil and gas fields and facilities, underground mines, processing plants, water treatment plants and power stations/substations.

With a thorough understanding of applicable standards and the underlying theory, GPA is able to guide clients through the arc flash assessment process and assist in tailoring a specific response to any hazards that arise to maintain client priorities.

GPA’s typical approach to arc flash assessment includes:

1. Power system modelling and fault level determination
2. Arc flash calculations to IEEE 1584
3. Risk assessment in line with NFPA 70E guidelines
4. Written analysis report
5. Working with the client to establish suitable arc flash responses and policies

GPA have provided a range of services in this space, including:

• High voltage and low voltage reticulation system modelling
• Network protection studies
• Arc flash incident energy calculations
• Identification of high risk scenarios
• Risk Workshops
• Labelling requirements

Arc flash assessments have been performed across a range of assets at a number of sites, including:

• BHP Olympic Dam
• Nyrstar Port Pirie
• Santos Cooper Basin
• Beach Energy Cooper Basin
• SA Water/Allwater operations throughout SA
• OZ Minerals Prominent Hill
• Territory Generation power stations throughout NT

GPA’s arc flash hazard analysis establishes the specific requirements to make each working environment safe. Our thorough approach, backed by experience and engineering knowledge ensures hazards will be identified and controlled effectively.
