This paper develops a simplified approach for the calculation of three phase short circuit current in radial low voltage LV networks. This method is based on data available at design stage, such as, voltage drop in cables and maximum design currents. It is an effective method for construction engineers in the field of electrical installation for checking the dimensions of switchgears and other equipment to withstand the thermal and dynamic effects of short circuits in site conditions.
