Walk-In Step-Up Transformer Substation - NAUVA

Step-up transformer substation designed for renewable energy applications (co-generation, hydraulics, biomass, wind and solar) and energy storage. These substations are used to convert, distribute and meter produced energy and to protect operations and the network.

Main characteristics

Concrete enclosure comprising:

• 50 to 3150 kVA step-up transformers
• LV main distribution board
• A GRANY modular MV board or NOGARIS fully insulated compact board (up to 42 units per substation)
• Substation protection and automations (monitoring systems, remote management systems, DEIE information and exchange device, GTC centralised technical management and modbus/Ethernet/optical fibre converter)
• MV network management equipment: ITI/PASA box or fault detection
• Auxiliary substation power devices: 48 Vdc backup source, MV power supply unit for auxiliaries equipped with a dry step-up transformer, dry LV/LV transformer
• Substation accessories: substation lighting, Enedis metering, heating, video monitoring, alarms, safety accessories, inverters, active filters, etc.

Advantages

• Sturdy substation: proven on-site manufacturing process certified by the energy distributor. Resistance to excess internal pressure that may occur in the event of an electric arc
• Customisable substation: variable transformer position (right or left)
• Attractive: optimised integration into all environments
• CAHORS synergy: all substation components are designed and manufactured within the group

Uses

• Renewable energy
