Equipment studies
Lead by highly skilled engineers with deep technical knowledge of transmission and distribution systems along with switchyards and balance of plants
Transmission lines and cables
- Design of resilient transmission lines corridors and routes (according to E&S and climat change contraintes)
- Design of High Voltage and Medium Voltage overhead transmission lines conductors cross-section (following economic, thermal, voltage drop, short-circuit current and corona effect criterion)
- Design of medium voltage cables as per IEC standard (layout selection, ampacity and cross-section calculation)
Switchyards, earthing and lightning protection systems
- Design of high voltage switchyards (bus bars arrangement and main equipment characteristics (circuit breakers, transformers, disconnectors, voltage and courrent transformers, surge arresters, compensation equipment)
- Techno-economic and cost-benefit optimization
- Design of the earthing system and grid for power plants, substations and transmission lines towers
- Design of lightning protection systems
- Soil resistivity and grid resistance inspection
Balance of plants
- Design of electrical auxiliary systems (arrangement and main characteristics of auxiliary services transformers)
- Sizing of direct current systems (Uninterruptible Power Supply - UPS)
