Derived Ratings (calculated from the configuration)

The values below are computed from what you selected above. Anything that cannot be computed yet is shown as an em dash — never as zero.

Iₙ = S / (√3·U) · I_sc = 100·Iₙ / uₖ · S_sc = √3·U·I_sc · I_p = k·Iₖ

Inputs taken from the configuration
Capacity: — kVAfrom the configuration above
System voltage: not specified
Impedance voltage uₖ: not specified

Rated current Iₙ—
Short-circuit current I_sc—
Short-circuit current I_sc—
Short-circuit power S_sc—
I_sc is calculated on the transformer impedance basis alone (system impedance neglected) — the same basis used in IEC 60076-5 short-circuit calculations.

Still required to complete the calculation: rated capacity S, impedance voltage uₖ, short-time or peak withstand current.

Per-model values (P0 / Pk / uₖ declared by the factory, losses, noise, temperature rise, dimensions, weight) are not in the product library: those rows stay at an em dash until the factory parameter sheet is supplied. An em dash means the value is unavailable — it is never rendered as zero.

Derived losses (from the selected efficiency grade + capacity)
No-load loss P0 (kW)—
Load loss Pk (kW)—

Read-only: no price factor, not part of the sum — the loss-grade cost is already carried by the efficiency (subtype) base price, so charging here would double-bill. Values come from the product library type-test data, interpolated between published capacities; grades the library does not cover show an em dash, never zero.

Reference prices are for estimation only and do not constitute a formal offer.
