Electricity Network - LV (Last update: 2021-01-21 11:59:36)

A low-voltage network (LV) is part of the distribution system that carries electric energy to end-consumers. The LV networks start from the output side of the MV-LV transformers. The transformers directly feed the different loads, thus constituting the last step in distributing electricity. The voltages used are 220/127 V and 380/220 V, which is regularly equal to the voltage of electric appliances.

The topology of these networks depends on the operation voltage, amount of required phases (3 or 1) and the required reliability. The electrical cables can be overhead lines, underground or a mix of both.
