Neutral reactance of wye(star)-connected winding in actual ohms.

May be + or -.

DSS property name: Xneut, DSS property index: 11

◆ XRConst()

bool dss::obj::Transformer::XRConst ( )

inline

={Yes|No} Default is NO.

Signifies whether or not the X/R is assumed contant for harmonic studies.

DSS property name: XRConst, DSS property index: 40

◆ Xscarray()

VectorXd dss::obj::Transformer::Xscarray ( )

inline

Use this to specify the percent reactance between all pairs of windings as an array.

All values are on the kVA base of winding 1. The order of the values is as follows:

(x12 13 14... 23 24.. 34 ..)

There will be n(n-1)/2 values, where n=number of windings.

DSS property name: Xscarray, DSS property index: 20
