Carrying out a survey is a complex, time consuming task. A methodical approach is required to ensure that mistakes are not made.
The task can be made easier by using one of the various software packages available on the market.
These packages can be a worthwhile investment as it will be found that the calculations may will be performed more than once whilst protection settings and work procedures are altered to reduce the hazard from an arc flash.
The downside to this kind of software is the amount of information required by it. A fault level study will also be carried out by the software at the same time.
If an accurate fault level already exists then cut down versions of the software packages are available or the spreadsheets contained within the IEEE1584 standard could also be used.
