In 1880, a European engineer and inventor theorized that the optimal three-phase transformer should have a symmetrical delta-shaped (3D) core. However, his theories could not be transformed into reality because there was no manufacturing technology available at the time that could make it commercially viable.
Remarks: All comparisons made using a 225kVA 3D wound core transformer and conventional stacked core under specific operating conditions unless otherwise stated.
Remarks: All comparisons made using a 1000kVA 3D wound core energy saving transformer (European standard Ao + Ak losses) and conventional stacked core standard loss transformer under specific operating conditions unless otherwise stated.
