measurement of transformer zero sequence impedance
(OP)
how to measure (test) the zero sequence impedance of two winding, three phase Dyn11 33/11 kV 15 MVA transformer?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

- 3 phase at delta side to be shorted together.
- 3 phase at y side to be shorted together.
- apply the voltage between one of the phases at y side and nutral.
- Z0 will be equall to V/I
