i have 28/32 MVA power transformer with 11/6.6 KC voltage
rating and 12%impedance.it have star connection at both
side.but it have another thied winding tertiary
winding.what is used of this winding.
pl tell me

Hi Paliwalsureshi,
Makers of such transformers usually provide a tertiary
winding connected in delta. This winding is sometimes called
compensating winding. As others have rightly said this
winding help to eliminate the harmoics which may interfer
with communication in power system. Before the advent of
microprocessor-based differential relays the old
differential scheme with star-star on one must have a delta
winging in between.In a nutshell any star-star connection
must have a delta tertiary.
