Nasıl hesaplandı

  • · Önek harfi: S = üç fazlı yağ daldırmalı, D = tek fazlı, SCB/SG = kuru tip (dökme reçine / hava).
  • · Kayıp seviyesi rakamı: 9/10/11/13/15/18/20/22 = verimlilik sınıfı (yüksek = daha düşük kayıp).
  • · Sonek harfleri: M = tamamen sızdırmaz, Z = yükte kademe değiştirici, L = alüminyum sargı.
  • · Sayılar: kapasite/YG[/AG] kVA ve kV cinsinden.
  • · Sondaki grup: Dyn11, Yyn0, YNd11, vb.

Sıkça sorulan sorular

What does S13-M-500/10 mean in a transformer model?

S = three-phase oil-immersed, 13 = loss/efficiency grade, M = sealed (full-sealed) construction, 500 = capacity in kVA, 10 = HV voltage in kV. So it is a 500 kVA, 10 kV sealed oil-immersed S13 Transformer. The calculator decodes the full model string.

What does SCB13-1000/10 mean?

SCB = three-phase dry-type cast-resin, 13 = loss grade, 1000 = capacity in kVA, 10 = HV voltage in kV. The 'B' denotes foil/band Winding. It is a 1000 kVA, 10 kV cast-resin Dry-Type Transformer. The calculator decodes SCB, SC, SG and other prefixes.

How do I read a transformer connection group like Dyn11?

Dyn11 = HV delta (D), LV wye/star (y) with neutral (n), and an 11 o'clock phase shift meaning LV lags HV by 30 deg (11 x 30 = 330 deg lead). Yyn0 = star/star with neutral and 0 deg shift. The calculator explains the Vector Group in the decoded result.

What do the letters S9, S11, S13, S20, S22 mean?

These are Chinese oil-immersed transformer series by loss level: S9 is the legacy standard, S11 and S13 reduce no-load loss ~20-30% step by step, and S20/S22 meet the current GB 20052 grade-1/2 efficiency. Higher numbers = lower losses and higher price. The calculator maps the series to its efficiency grade.

Why do I need to decode a transformer model number?

The model number encodes type, cooling, capacity, voltage and loss grade in a compact string, so decoding it lets you verify a quote, compare tenders, or match a replacement. Misreading a digit can lead to a wrong-voltage or wrong-capacity purchase. The calculator decodes the string into plain fields.
