Effect on Secondary Voltage in Connection Star and Delta of a Trans
Effect on secondary voltage of 6.3KV primary delta to secondary delta step up 11KV transformer transformer secondary delta connection into star connection is replaced?

My question is to everyone, especially to Mr. Phil c, is what will be the effect on secondary voltage of 6.3KV primary delta to secondary delta stepup 11KV transformer if we replace transformer secondary delta connection into star connection?

I am very much obliged to Mr. Phil Corso for his prompt reply. Posting here for information other colleagues.

Shaheed,
Regarding your question on Control.Com, "Reconnecting Sec'y of a D-D Xfmr, to D-Y Xfmr." My answer is when sec'y is reconnected from 'D' to 'Y', then, sec'y ph-ph voltage becomes 19kV.

Regards, Phil Corso

Ps: Is this the same Xfmr you asked about in 2012?
