Introduction
DER can impact arc-flash in three ways:
- Contribute fault current and hence increase the fault current levels
- Contribute fault current, which reduces fault current from upstream slowing fault clearance time and increasing arc energy
- Grounding banks provide another ground source which can slow down pstream zero sequence overcurrent elements, delay fault clearance and increase arc energy
