AC change path called frequency having 0 to 360 degree and
all alternator phase sequence design at 120 degree
differences ie 0/360 - 120 - 240 Degree universal in
3 phase sequence called R Y B

Answer / karun

We can transfer power 2 or 3 or 4 phase but we know that
actually power generation is done in 3 phase it is economic.
If we want to transfer 4phase we should generate power from
different generators.
and i agree this answer

When we change the tap position of 10MVA transformer it suddenly tripped with Out of step indication and also with Static differential relay indication, Transformer Bucholz relay indn and Low oil level indication. Before 1 week the same problem occured by changing the tap position. but at that time only oltc bucholz relay activated. After testing the TxR Relay team & PET team cant find any solid reason. The values are ok also. So plz answer wat's the reason for this incident? anybody plz help.
