Hello there,

We recently bought a copy of the new IEEE 1584-2018 Version and we are using excell spreadsheets as well , since new softwares will only be purchased next year.If you do not mind ,have you gone through the sample calculations in the new IEEE-1584 2018 Standard ?

On page 74 of the standard, I am getting higher values of incident energy i.e 65.23 J/mm2 instead of the 53.156 shown in the example.I tried checking more than ten times and I see nothing wrong on my spreadsheet.Did you get it right , if yes, then I know Im definitely doing something wrong.

Appreciate your response.

Thank you

Regards

Ashford

Updated software based on the new IEEE 1584 has been rolling out. Spreadsheets are being created as well as other homegrown solutions. Some have even performed the calculations by hand (we do this in my arc flash class). So here is this week’s question: (Select all that apply) Have you begun performing arc flash calculations based on the new 2018 edition of IEEE 1584? Yes – with software Yes – with spreadsheet or other method Yes – by hand No – not yet

We are currently using this new version of IEEE 1584. All new projects quoted since November have been quoted using the new version. For projects that we have started but not yet completed, we have sent a letter to the customers asking what version of IEEE 1584 would they like us to use. Since there is more labor involved using the new version, we are providing a cost adder (change order).

No. Currently using an Excel based calculation (calculator) self developed from information and formula from the NFPa 70E and IEEE 1584 (2015 version). Already busy for two years and will use 2018 version with the next set (within the 5years update) The reason is that no funds are available to buy specific software available. This was excepted by management.
