Cara perhitungannya
- · Huruf awalan: S = tiga fasa terendam minyak, D = satu fasa, SCB/SG = tipe kering (resin cor / udara).
- · Digit tingkat rugi: 9/10/11/13/15/18/20/22 = kelas efisiensi (lebih tinggi = rugi lebih rendah).
- · Huruf akhiran: M = tersegel penuh, Z = pengubah tap saat berbeban, L = belitan aluminium.
- · Angka: kapasitas/TT[/TR] dalam kVA dan kV.
- · Grup akhiran: Dyn11, Yyn0, YNd11, dll.

Pertanyaan yang sering diajukan
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.
