Example of HV urban links:GIL, GIS, whisper transformer
Whisper transformere.g. New York• 420 MVA, 345 kV• Noise level of only 57 dB(A)
– 20 dB(A) lower than standard design
GIL (Gas Insulated Line)e.g. PALEXPO, Geneva, Airport Frankfurt• Transmission behavior similar to overhead lines• Very low electromagnetic emissions
GIS (Gas Insulated Substation)e.g. Moscow• Space-saving installation • Improved security of supply• No interruption of power supplies during conversion• Possibility of grid expansion
