Site condition:
-Three phase inverter
-Negatively grounded
-1500v array configuration with a VOC of about 1370 volts that under load is about 1185 volts
-GFDI fuse has trigger pin but intended switch fails to see pin activated
-Fault is a DC fault of about 890 volts constantly neg to ground
-Inverter never tripped but would continue to produce power
What would be the affects on the utility side of the pad transformer.
high side is wye and low side is open delta (ground not tied to any phase for a reference), I believe is what the terminology is referencing.
