DC Arc Flash Calculations


Your local IEEE FWCS PES/IAS Chapter will host a webinar on the topic of performing “DC Arc Flash Calculations”.  We will cover the three most common methods for performing calculations:

  • Maximum Power Transfer Method
  • Stokes & Oppenlander Arc Resistance Method
  • Paukert Arc Resistance Method

Additionally, we will discuss the difference between methods when applied to a voltage sourced system compared to a photovoltaic sourced system.  Lastly, we will discuss some test results of PV systems and compare to the various calculated models to determine how accurately the models estimate actual incident energy levels on PV systems. 

This event will provide four (4) CEU/PDHs.
