Slot: MVAsc3¶

MVA Short circuit, 3-phase fault. Used to derive positive-sequence impedance.

Comments¶

Import fallback, used only when R1/X1/R0/X0 are not all given: Z1 = basekv² / MVAsc3; r = Z1 / √(1 + x1r1²); x = r × x1r1 (x1r1 defaults to 4.0 if not specified). Not stored directly on CIM; r and x are the canonical fields and are always written back on export via R1/X1 — MVAsc3 itself is not exported.
