·The DC-DC Transition
Grounding, bonding, and DC ground-fault protection at 800 VDC (DC-DC Transition V)
Grounding topology at 800 VDC is a Stage-1 architecture decision that interacts with arc-fault protection and insurance. TN-S vs IT-System has different scaling properties at hyperscale. Insulation-resistance monitoring runs into engineering limits above 100 MW connected load.
