Carbon insight
Upgrading from "S13 — oil-immersed (grade 3)" to the lowest-carbon "Amorphous alloy — oil-immersed" would avoid ≈ 4,906 kWh and ≈ 2.94 tCO₂ per year at this load factor — subject to the actual nameplate losses and the local grid emission factor.
Note
Losses use typical values (GB 20052 / industry references) scaled from 1000 kVA — always verify against the nameplate. Output energy assumes PF = 1 (kVA × PF × load factor × hours). The grid emission factor varies by region (≈0.2–1.0 tCO₂/MWh); adjust it to your local grid for a meaningful result.

Nasıl hesaplandı
- · Yüksüz kayıp enerjisi = Po × saat; yük kayıp enerjisi = Pk × LF² × saat.
- · Yıllık kayıplar = Po × saat + Pk × LF² × saat.
- · Verimlilik = çıkış ÷ (çıkış + kayıplar), çıkış = kVA × LF × saat.
- · CO₂ emisyonları = yıllık kayıplar × şebeke emisyon faktörü.
- · Kayıplar 1000 kVA referansından Po ∝ S^0.75, Pk ∝ S ile ölçeklenir.

Sıkça sorulan sorular
How do I calculate transformer CO2 emissions?
CO2 = annual losses (kWh) x grid emission factor. No-Load Loss runs 24/7: a 1000 kVA unit with 1.2 kW no-load loss consumes 10,512 kWh/yr just sitting energised. At a 0.5 kg/kWh grid factor that is ~5.3 t CO2/yr. The calculator sums no-load and load losses and converts to carbon.
What efficiency level should a transformer meet?
Distribution transformers are 98-99.5% efficient at full load. GB 20052 and IEC 60076-20 set minimum efficiency/loss grades; choosing a higher grade (S13/S20, SCB13/SCB14) cuts no-load loss 20-40%. The calculator compares efficiency levels and their loss and CO2 impact.
How much energy does a transformer waste in a year?
A 1000 kVA Transformer at 50% load with 1.2 kW no-load and 8 kW full-load loss wastes about 1.2x8760 + 8x0.25x8760 = 28,032 kWh/yr. A lower-loss S13 model can cut that 15-25%. The calculator quantifies annual losses and their cost.
What is a good load factor for transformer efficiency?
Peak efficiency occurs where load loss equals no-load loss, often 40-60% loading for distribution transformers. Operating far below this wastes no-load loss; far above raises Copper Loss. The calculator shows the efficiency curve and the optimal loading point.
How do I compare two transformers on lifetime carbon?
Compare annual losses x lifetime x grid factor, plus embodied carbon from materials (copper, steel, oil). The loss-driven operational carbon usually dominates over 20-30 years. The calculator computes operational CO2 per model so you can rank S11 vs S13 vs amorphous.
