How to energize a photovoltaic plant?

Using the fully pre-assembled and tested xSolAir substation, all it takes to energize a photovoltaic plant is to connect the medium voltage cables to the medium voltage switchgear. Covering every aspect of power management xEnergy Main low voltage system Xiria SF 6

Can a ring main unit be used for a medium voltage grid?

The solution to medium voltage grids rated up to 36 kV. On the medium voltage side each container can accommodate one ring main unit for a connection to a medium voltage/low voltage transformer. The ratings of both the ring main unit and the medium voltage / low voltage transformer can be selected as required.

Which GIS products are available in the medium-voltage room?

The medium-voltage room contains a Brunstock gas-insulated secondary ring main unit. Read more about our green GIS products, which contain dry air: BGS-12 and BGS-40.5. We also offer BGS-24, which contains SF6 gas. The circuit breaker offers transformer protection mainly through the relay protection device.

Which switchgear is best for solar projects?

The ideal option for solar projects is our compact LLC switchgear series, with a length of 1907 mm for the 36 kV version and of 1654 mm for the 24 kV version. Safe, reliable and easy to use: • Simple and easy- to-use mimic diagram. • Straightforward design, clear instructions of use. • Optional SCADA interface.
