Post subject:  Solidly Grounded vs. Ungrounded Systems - Arc Flash Safety

Hi,

Just curious if anyone has an opinion regarding risks, issues with grounded system vs. ungrounded system in the context of Arc Flash Safety. Specifically, for older delta distribution system that has no ground fault detection. Is the arc flash study conduct the same way. We are looking to use contractor to do the work, however, from an education standpoint, I am new to arc flash and just wanted to expand my understanding.

Regards,

DP
