| General comment on data set | ecoQuery: https://ecoquery.ecoinvent.org/3.10/cutoff/dataset/5835/documentation This dataset represents the transformation of electricity voltage from medium to low voltage. The losses are based on electricity generation and trade statistics: IEA World Energy Statistics and Balances, ISSN: 16834240, https://doi.org/10.1787/enestats-data-en Definition of the voltage levels: - High voltage level above 24 kV (large scale industry) - Medium voltage level between 1 kV and 24 kV (medium to small scale industry, service sector and public buildings) - Low voltage level below 1 kV (Households) This activity starts with the medium voltage electricity arriving at the transformer station. This activity ends with 1kWh of medium voltage electricity transformed to low voltage. This dataset includes the losses during voltage transformation. It doesn't include the transformer station itself as this is included in the dataset for the transmission network. |

| Technology description including background system | Transformers are essential components of the electricity grid. They connect the different voltage levels.;Big power plants feed the electricity at a very high voltage to the electricity grid. Transformers between 600 MVA and 80 MVA can be found in substations, where the high transmission voltage is transformed to the medium distribution voltage. In an additional step the medium voltage is transformed to low voltage using transformers below 2.5 MVA. The small transformers below 2.5 MVA are allocated to the low voltage level, whereas all the other transformers are allocated to the medium voltage level. |
