Three winding transformer regulation
Three winding transformer regulation
(OP)
Dear Folks,
I am looking for an AVR, which can able to regulate the voltages at both secondaries of three winding transformer. OLTC is located on primary winding of the transformer
If such AVR available, please suggest me.
Advanced thanks.

If, both PT and CT of both secondaries are connected to AVR, and AVR is programmed such that it should choose optimum tap position for both secondary windings regulation. If there is huge load difference in both secondaries and optimum tap position cannot be choosen, then AVR should regulate preferenced secondary winding voltage.

I'm not shure if some company have such AVR, but, you can check this issue with :
1. Tapcon 245/250/260 from MR company.

2. REGsys from Eberle company.

From my point of view you have build some external logic with .. PLC and use two separated AVR with common command to one OLTC via this PLC.

We forgot ask you. Secondary voltages are same?
