What it calculates
The “Per-Unit System” calculator computes Z per-unit from 3 parameters: z, ω, v_base, kv, s_base, mva.
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters Z, Ω = 1, V_base, kV = 10, S_base, MVA = 100 the result is 1 (Z_pu = Z / (V_b²/S_b)).
