| Notes | Selection of the correct tap Ordering example for single-phase transformers
I = S/U I = Current S = Apparent power U = Voltage of the tapping I = 250/22 = 11.4 A ￫ +ZA16 For the secondary tap, the correct suffix is: +ZA16S(22)A primary side additional tapping is determined in the same manner. Ordering example for three-phase transformers
I = S/√3 x U) I = Current S = Apparent power U = Voltage of the tapping I = 250/(√3 x 22) = 6.6 A ￫ +DZA16 For the secondary tap, the correct suffix is: +DZA16S(22)A primary side additional tapping is determined in the same manner. |
