Trafo Yüklenme Oranı Nasıl Hesaplanır?
Transformer loading, It is the ratio of the apparent power drawn (S_load = P/cosφ) to the rated power.: %yüklenme = S_yük / S_anma × 100. Örneğin 1000 kVA trafodan 620 kW (cosφ 0,9) çekiliyorsa görünür yük ≈ 689 kVA, yani ≈ %69 yüklenme. Sürekli çalışmada tipik uygun aralık %40–80’dir.
Transformer Load Ratio (%)
Calculate the transformer's percentage load and secondary current based on its rated power; identify over/under loads.
How is it calculated?
- Enter the transformer power (kVA) and secondary voltage.
- Enter the active power drawn (kW) and cosφ.
- Press Calculate; the load %, apparent load, and secondary current will be displayed.
