Zero Sequence Impedance for Series Reactors

[newpower]

I've read Thread238-21974 and I think this may be useful for shunt reactors, I was curious if there are some ballpark numbers for estimating zero sequence impedance given positive sequence impedance.

Specifically, we are installing a 1.75 ohm reactor at 34.5kV. We are modeling it on a 100 MVA base with a positive sequence reactance of j .147 (per-unit).

I am trying to figure out how to model the zero sequence reactance. If anyone can provide guidance, it would be greatly appreciated.

Also, this information is supposed to be available from the shunt reactor manufacturer.
