Hello. I am conducting a DC arc flash hazard assessment on a PV power plant, and I plan to adapt the methodology of determining the incident energy of a DC electric arc that Yuventi (2014) proposed in his paper (https://ieeexplore.ieee.org/document/6676858).
Aside from determining the working voltage and current of a PV string/array, it involves the BACK-FEED CURRENT that apparently comes from the PV inverter, as part of determining the arc current, which contributes to the incident energy of the DC arc.
My question is, how do I determine the BACK-FEED CURRENT that a PV inverter may return to the DC portion of the PV power plant during fault? Do I look at the data specs of the inverter?
Hoping that you guys could help me out. Thanks in advance.
