Tag:power=substation - OpenStreetMap Wiki:power=substationHow to Map. Tag a or a as power = substation.Most substations should be mapped as areas. Very small substations such as small transformer kiosks in residential areas may be mapped as substation nodes, or as transformers.. In a few cases, a single substation is split over multiple sites (for example on either side of a road), and should be tagged as a multipolygon relation.

NEW CONCEPT FOR MEDIUM VOLTAGE GAS INSULATED …· PDF fileHistorical steps towards total freedom from maintenance in circuit breaker switchgear. Gas-filled switchgear with maintenance-free HV sections Nearly 20 years ago, in 1982, the first gas insulated medium voltage switchboard with vacuum circuit breakers was introduced . Compared with air insulated equipment, it had significant advantages:
GIS and hybrid switchgear technology - EE Publishers above approach requires minimal consumption of SF6 gas as only VCB and DS is only in SF6 gas unlike conventional GIS switchgear where all HV compartments are in SF6. By using this approach, the SF6 consumption is reduced to 1,5 kg for up to 24 kV and 4,5 kg for 36 kV switchgear respectively.
