## zero sequence impedance of an inverter

## zero sequence impedance of an inverter

(OP)

Can someone describe the zero sequence impedance of an inverter? I've heard it described as a delta winding in a transformer, so it is just an open circuit. So if I have a generator or photovoltaic array behind it, it doesn't matter since the open circuit is there for the inverter.

Can someone validate this assumption. Thanks.

If I have a delta grd-wye isolation transformer, then I get a break or open in the zero sequence. So I get no contribution from the inverter for a single line to ground fault on the primary or secondary of the stepup transformer. Is that what you're getting at?
