Autotransformer 220/115/38.5kV + compensation winding
(OP)
Hi all,
Please somebody to say me, Is it posible Autotransformer with 3 work voltage + compensation winding (6kV)?
If it is posible, please say me What will be vector group of such autotr-r....YNynaO+d may be?

RE: Autotransformer 220/115/38.5kV + compensation winding
Primary Voltage: 161 kV RMS, wye connected to a 161 kV grounded wye system. The 161,000-volt winding shall have full capacity taps at:
173,075 Volts
169,050 Volts
165,025 Volts
156,975 Volts
Each transformer shall have an externally operated no-load tap changer.
Low Voltage: 4.16 kV RMS, wye for 3-phase units connected to a 4.16 kV grounded wye system.
Tertiary: 4.16 kV RMS, wye for 3-phase units connected to a 4.16 kV grounded wye system.
Medium Voltage “Stabilizing” Winding: 13.8 kV RMS, delta connected. This winding shall be provided for the circulation of third harmonic currents and stabilization of the neutral. This connection shall never be changed. No external load shall be taken from the MV winding.
