Slot: MVAsc1¶

MVA Short Circuit, 1-phase fault. Used to derive zero-sequence impedance.

Applicable Classes¶

Comments¶

Import fallback, used only when R1/X1/R0/X0 are not all given and MVAsc3 > 0: Zs = basekv² / MVAsc1; Z0 = 3×Zs − 2×Z1; r0 = Z0 / √(1 + x0r0²); x0 = r0 × x0r0 (x0r0 defaults to 3.0 if not specified). If MVAsc1 is absent, r0/x0 default to r/x instead. Not stored directly on CIM; r0/x0 are the canonical fields and are always written back on export via R0/X0 — MVAsc1 itself is not exported.
