Preferential Subject 2 – “Acceptable Functional Integration in Substation P&C for Transmission Systems”
Question PS2-11Is any user already planning to employ the “two boxes per
bay” solution in transmission, or the “two boxes per substation” system?
Are there equipment available in the market? When can these solutions be adopted?
Which are the advantages and disadvantages or obstacles?How can these obstacles be overcome?
