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

Answer Posted / manish meena

tertiary winding used for,
-to obtain additional voltage
-to stabilize neutral in case of star/star transformer
-to reduce third harmonics and control zero sequence
impedance.
