Zero Sequence Voltage 3Vo
Zero Sequence Voltage 3Vo
(OP)
Is Zero Sequence Voltage detectable through a Delta transformer winding? It appears that the Delta would block it the same as zero sequence current?
Is there any good references on applying zero sequence voltage protection settings?

There also an article on the Basler web site about open phase detection which I believe discusses zero sequence voltages. I can't find it now because their site is down.

An grounded-wye/[b]broken[/b]-delta transformer set is one simple ‘zero-sequence filter’ used for 59N/59G ground-detection protective relaying. The Stevenson text and GE IAV and Allentown 59G relay ILs discuss applications on ungrounded and high-resistance-grounded systems.
