ImpedanceCorrectionData
Package: PowerOperationsOpenAPIModels · Source: Operations/SupplementalAttributes/ImpedanceCorrectionData.json
Supplemental attribute carrying one row of an impedance correction table, linked to a transformer. Exactly one correction curve is present, selected by transformer_control_mode: tap_ratio_correction_curve spans off-nominal turns ratio and phase_angle_correction_curve spans phase-shift angle. transformer_winding names the winding the row applies to.

tap_ratio_correction_curve | PiecewiseLinearData | — | 1 | Impedance correction factor as a function of off-nominal tap ratio (x axis in tap ratio, y axis a multiplier on the winding impedance). Present only when transformer_control_mode is TAP_RATIO. Units: 1. |
phase_angle_correction_curve | PiecewiseLinearData | — | rad | Impedance correction factor as a function of phase-shift angle (x axis in radians, y axis a multiplier on the winding impedance). Present only when transformer_control_mode is PHASE_SHIFT_ANGLE. Units: rad. |
