Description

Location: JP - Japan
This dataset represents the transformation of electricity voltage from high to medium voltage.
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)
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.

Technology

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.
