Features of completed substation/box substation
Common power ratings:
30, 50, 80,100,125,160, 200, 250, 315, 400, 500, 630, 800, 1000, 1250, 1600, 2000, 2500 kVA.

This transformer is designed for voltages of ≤ 36 kV. 

Specific figures are not given for this parameter because of the wide variety of voltages used.

 Transformers can be supplied on demand to run at two different primary voltages, the shift between these input voltages has two
basic alternatives:
• with a primary tap changer which can be switched with no load and no applied voltage
• or by changing terminals under the cover.

The secondary voltage under no load is allocated at 400V, 415V, 433V, though other voltages can be supplied on demand.
When usage requires two voltages, transformers with two simultaneous voltages can be supplied. 

In this case the no-load voltages are set to 400V(230V),415V(240V),433V(230V) .

As per IEC /BSEN 60076 standards these are
set in accordance with the highest voltage for the material,
being the level immediately above the rated voltage.
