Short-circuit current calculation according to DIN VDE 0102 (issue 2002) in planning and operation of an urban distribution system

In electricity supply systems, short circuits can cause damage to the equipment, endanger human lives or interrupt operations. The dynamic and thermal stresses from short circuits play a major role in the dimensioning of stations and equipment. This is why the calculation of short circuits is so significant in planning and operation when it comes to the safety and profitability of electricity supply systems. Both maximum (station design) and minimum (protection equipment parameter adjustment) short-circuit currents must be defined for all relevant technical and operational situations in the systems. The necessary calculation methods should provide the most accurate and safe results with a minimum complexity.
