Arc Flash Assessment and Mitigation

Providing a safe environment surrounding electrical infrastructure is mandatory as stated in various Acts, Regulations, Standards and Codes. During an electrical fault, shock hazards are present and the energy released can cause an Arc Flash. Management of electrical shock hazards is a fundamental principal of electrical safety, however the arc flash can result in electrical burns, flying debris and toxic gas hazards. Management of the arc flash hazard is not directly covered as an essential principal of electrical safety with awareness covered only.

U.S.E. performs a review of your existing or proposed electrical infrastructure for Arc Flash hazards focusing on adopting control measures only when necessary with the inclusion of the assessment of ‘Do Nothing’.

U.S.E completes power system modelling of your electrical infrastructure with accurate and verified data entry including cables, transformers, protection devices, protection settings and operating clearance times. Using industry standard IEEE1584 calculations determining the potential arc flash incident energy,  U.S.E. provides verification of these calculations and determines the arc flash hazard including defining exclusion zones for the various operating and maintaining states. Using our real world experience, we review control measures (Elimination, Administration, Engineering, PPE) and adapt the control measures to enable our client to continue to operate the infrastructure as originally intended.

We can design and through our partnerships arrange the implementation of mitigating control measures such as:

– Revision of Protection device settings

– Revision of Fuse Sizes

– Installation of Arc Fault Detection Devices

– Shunt Trip or Undervoltage Trips of existing devices

– Installation of Differential Protection Schemes

– Replacement of upstream protection devices

– Establishment or revision of PPE requirements based on NFPA70E and AS4836.
