Low-voltage distribution lines refer to the circuits that, through a distribution transformer, step down the high voltage of 10 kV to the 380/220 V level—i. Electrical equipment fed directly from the low-voltage mains Specificationofaspecificovervoltage category shall be based on the following: –Equipmentofovervoltage category I is equipment that is intended to be connected to the permanent electrical installationofabuilding. Some links are removed, so that each (fused) distributor leaving a substation forms a branched open-ended radial system, as shown in Figure C4 In European countries the standard 3-phase 4-wire. ents), and the electrical equipment, formed by the internal connections and by the incoming and outgoing termina is regard, there has been an evolution which has resulted in the replacement of the previous Standard IEC 60439 with the present Stand rd IEC 61439.
