As with all risk assessments, an arc flash survey should be periodically reviewed, for example every 2 years.
The length of time will depend upon the nature of the installation.
The following occurances should also trigger a review of the assessment irrespective of the time scale.
  • Change in supplier fault levels
  • Additional sources of supply to installation
  • New switchgear fitted or existing altered
  • Alterations to protection settings
  • Change in transformer impedances
