How to make calculation for distribution substation 10/0.4, 2 x 1600kVA

Distribution substations with an installed power of 2ร—1600 kVA are a typical example of electrical power supply facilities which can be often seen all around Europe and wider. By “calculation” of such a substation, it is assumed that values of all relevant physical quantities shall be determined, and all major equipment inside the substation shall be specified according to these values.

Within this article, an example of this type of calculation for electrical equipment will be given.

A basic guide for calculations and dimensioning will be adequate IEC standards and practical engineering experience. Of course, besides electrical, there will be also civil and HVAC (Heating Ventilation and Air Conditioning) requirements for substation which need to be fulfilled, but they are out of the scope of this article.
