The saturation characteristic of the magnetizing flux paths are specified via the open-circuit test results in pairs of per-unit current and per-unit voltage (Ipu, Vpu). The first point should be (0.0, 0.0) and the second point should be (I2M, V2M), where I2M is the current in per unit at which the onset of saturation occurs and V2M is the corresponding per-unit voltage and should be equal to I2M(XL0+XM0). Inconsistency will result if V2M does not satisfy this condition.
A maximum of 10 pairs can be specified. If less than 10 pairs are used the last pair must be (-1.0, -1.0) and the points thereafter are ignored.
