IEEE 1584-2018 Arc Flash Incident Energy Calculation Method using ETAP

etap.com/arcflash - This webinar provides an overview of the fundamental differences and changes between the IEEE 1584-2018 and existing arc flash calculation methods. To better understand how the 2018 model combines empirical and arc flash physical behavior, the video covers background and insights into the model development validation.

very nice, good to see more webinar in future

Thank you for your interest in ETAP Software and your positive feedback

Thank you for your presentation. I do have a question, since IEEE 1584-2018 scope includes systems with voltages from 208 v to 15 kV only (and it no longer recommends Lee Method for V≥15kV), what method are you using in ETAP to calculate incident energy in systems with voltages greater than 15 kV? (Currently I am doing an arc flash study in a 34,5 kV switchgear, three-phase). Thanks.

@@ETAPsoftware Mr. Jose Cardozo is not saying he is interested in ETAP. In case you did not understand his question, let me repeat it for you: what method are you using in ETAP to calculate incident energy in systems with voltages greater than 15 kV?
I am interested too in your reply but i know it is suggested in IEEE 1584-2018. Thank you!

ETAP has a solution for your application and it is subjected to some more specific details concerning your system and needs. The best approach is to call ETAP help center or our sales team ([e-mail]) to get a concise response meeting your needs, as we do have some proprietary information that cannot be shared in a public domain. Feel free to open a request in help center or contact our sales department for more details

At the 52:15 you begin to explain the top of the circuit breaker being a VCBB but the bottom being a VCB type? Are you using the top of the circuit breaker as an "insulation shield" in the event of an arcing event? But what if this circuit breaker was installed closer to the ground and not at eye level would the classification be reversed since the head and torso are now "shielded"? Thank you in advance.

[@ETAPsoftware]

Hello Michael, thank you for your interest in ETAP. I forwarded your question to our Arc Flash team, which I trust will get back to you shortly. In the meantime, you can also log into our HelpDesk 24/7 and raise your question with our support engineers.

The top configuration was VCBB because the breaker itself can be a barrier (i.e) a tool may come in contact between the conductors and the arc plasma can shoot towards the working personnel due to the breaker being a barrier to push it forward. However, irrespective of double configurations, ETAP can support both configurations defined in the enclosure editor and the final incident energy calculation will be based on the worst case incident energy.

love it

[@saadmudassar5148]

sir can u gude me about Arc Flash sequance why can breaker cannot operate in Arc flash sequance analysis??? kindly guide me about this situation...............how it can taggle in etap 16.0.0

[@jeremypangilinan748]

Hi Saad. The sequence of operation tool is available when 3 Phase Arc Flash is selected in the study case editor. Please confirm you have selected this.

[@ragoo07]

Saad, There are many reasons for this behavior. If it is not properly interlocked to a protective relay or if the fault is on a location for which the same breaker cannot be a source protective device (PD) . For Arc flash , The clearing time (Arc duration) is based on arc current seen by the Source PD which is in the path of the source contributing it to the fault.
