Arc Flash Consultancy & Training


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

Our aim is to provide practical and actionable advice that maximises a safe operating environment and work practices for workers across Australia's wind and solar sites. Arc flash calculations are prepared for the primary power components and primary switching locations. Our engineers utilise the ETAP AC 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.
