Would it be valid for me to assume then, that this means SLG faults and effects are generally NOT included in most arc flash studies at this time ?
Yes. The assumption is that SLG faults will progress into 3P faults and that 3P arcing faults have more energy than SLG arcing faults.
An exception would be electric utilities where the NESC arc flash hazard tables (above 1 kV) were developed assuming SLG faults. This is because of larger phase spacing on OH lines compared to typical industrial enclosed equipment.
