Arc Flash

Arc Flash Consultancy

Thomson Bridge prepares arc flash calculations, reports and recommendations for generation and infrastructure assets such as turbines, collector groups and balance of plant.

Our aim is to provide practical and actionable advice that maximises a safe operating environment and work practices. Arc flash calculations are prepared for the primary power components and primary switching locations. Our engineers utilise the ETAP Arc Flash Analysis software to perform the assessment of arc flash hazards and incident analysis. 

We work with our clients to consider critical factors including system power distribution configuration, plant operating modes, protective equipment selection and settings, working distances, PPE, work practices and training.

Our Arc Flash services are delivered by an experienced team of electrical, power system and protection engineers. Our clients own and manage portfolios of generation and infrastructure assets across Australia.  

Thomson Bridge was also the lead author of the Electrical Arc Flash Hazard Management Guideline which was published by the Australian Energy Council.
