Context
Project Type :
Temporary Energy
Location :
Ribeauvillé (68)

Problem
- The customer had to undertake pruning work downstream of an HVA line to secure their mains
- To do this, they had to stop the source substation supplying an aerial (network point)
- ENEDIS wanted a solution to supply their network at 20 000 V and avoid any power cut for its users
- The feasibility study had to take into account a tight installation site on the edge of the road
Solution
- Supply, installation, testing and commissioning of a Micro Plant 20kV of 500 kVA:
-
- Generator 500 kVA
- 1 transformer HVA 2 000 kVA on semi-trailer
- 1 tank of fuel 3 000 L
- Mains protection provided by a neutral point coil and realisation of a grounding circuit
- Continuous energy production over 8 hours
- Duration: 1 day of operation
