In general, the electric power system in Switzerland can be divided by voltage levels: extra high voltage (EHV), high voltage (HV), medium voltage (MV) and low voltage (LV) networks. The locations and number of EHV stations are publicly available at ENTSEO (https://www.entsoe.eu/data/map/), whereas other are not. So, is there any database which can provide details on either for HV, MV or LV network? Thanks in advance.
