In fact electrical network design is often a key requirement set out to select the section of the wire and then check the remaining requirements. For example, overhead line conductors of electricity transmission network are selected according to economic criteria and test specifications, whereas conductors in distribution networks selected according to conditions allowed voltage loss, conductor in enterprise networks selected according to conditions of heat ...
electricity distribution network load by more direct questions via transformers should not ask about the quality of the voltage very closely, on the other hand the ability to adjust the voltage the distribution network is also limited compared to the transmission network. Therefore, when designing the distribution network is often based on the level of voltage loss for the section to select the wire.
