02 Nrụpụta

2.1 Isi

Core uses CRGO silicon steel, perfectly matched to 1500kVA, 5.0/0.48kV, Dyn1, 60Hz (no‑load loss 1.545kW, load loss 10.540kW). Design & manufacturing comply with IEEE C57.12.34-2022, C57.12.00-2021 & C57.12.90-2021. Tests confirm: max turns ratio deviation +0.16% (well below 0.5%), losses and impedance meet guaranteed values. Quality: five‑step step‑lap process reduces eddy losses and noise; core clamped and coated against moisture/rust. Highlights: step‑lap cuts no‑load current ~12% and transverse leakage >50%; 45 ogo nkwonkwo mitered ezigbo flux steering.

2.2 Ikuku
