Utility – Power transformer of generation (nuclear, thermal, hydro), transmission and distribution with a total of 1.093 transformers.
Namepale data of transformers:
Power max [MVA]: 760
Voltage max [KV]: 400
Oil mass [Kg]: 75.000 each
PCB max [mg/Kg]: 5.000
PCB target [mg/Kg]: < 20 (after 90 days)
Solution Sea Marconi
Solution: Dehalogenation treatment (CDP Process®) in order to remove the PCBs from oils and transformers. The treatments were performed off-load and on-load (transformer fully load during the treatment).
