Notes Selection of the correct tap

Ordering example for single-phase transformers

  • selected transformer STZ0,25(400/24)
  • required voltage of additional tapping 22 V
  • the current for selection of the tapping is calculated as follows:

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

  • selected transformer DTZ0,25(400/24)
  • required voltage of additional tapping 22 V
  • the current for selection of the tapping is calculated as follows:

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.
