The consumer substation with MV metering
From Electrical Installation Guide
A consumer substation with MV metering is an electrical installation connected to a utility supply system at a nominal voltage usually between 1 kV - 35 kV, which for example may supply:
- A single MV/LV transformer exceeding generally 1250 kVA
- Several MV/LV transformers
- One or several MV/LV secondary substations.
The single line diagram and the layout of a substation with MV metering depend on the complexity of the installation and the presence of secondary substations.
For example a substation may:
- Include one single room containing the MV switchboard, the metering panel, the transformer(s) and the low voltage main distribution board(s),
- Supply one or several transformers, each installed in a dedicated room including the corresponding main LV distribution switchboard
- Supply one or several secondary MV/LV substations.
