Is anyone Familiar with the NENS 09 Australian AF Calculation method?

Hello,

Is Anyone out there familiar with the NENS 09 Australian AF Calculation method?

This method was published in the "ENA NENS 09-2014 National Guideline PPE Arc" Guideline that's used in Australia. (See equations below)

They list the methodology and equations but I don't see a breakdown of the method limitations.



For example, in IEEE 1584 there is a disclaimer saying the applicable voltage, fault currents, etc that the method is valid for.

Based on the citings this method may have originated from the following document but i can't seem to find it anywhere online.

EESA Electrical Arcing Hazards - A paper by Dr. David Sweeting (Sweeting Consulting) and Professor Tony Stokes (Electrical Engineering University of Sydney) presented at the EESA Conference in Sydney on 12 August 2004;

If anyone can shed some light on this or point out the limitations of the method that would be appreciated!

I realize the method is older in comparison to IEEE 1584 but im interested to see how the assumptions of this method compare to the updated IEEE 1584 model.


RE: Is anyone Familiar with the NENS 09 Australian AF Calculation method?

What is this for and where is it applied?

Hello Mbrooke,

The equations are used to estimate the incident energy if an arc fault event takes placed.

I dont know if its widely applied at the moment.

Its just a methodology i ran into when trying to find different Arc Flash Analysis methodologies.

My end goal is just to see how it compares against established methods like IEEE 1584 and what are its limitations/application ranges.
