Tap Changer Controller with Master-Follower mode
Tap Changer Controller with Master-Follower mode
(OP)
Can people suggest a manufacturer of xfmr tap changer controls for large autos in high voltage applications, that supports xfmr paralleling and master-follower arrangements? I want SCADA to be able to remotely sets the tap of one xfmr, and I want the tap on the parallel xfmr to blindly follow (maybe based on minimizing circulating current, ignoring voltage regulation). (Beckwith tech support reports they do not have any means to support master follower tap changer logic, so I am looking for an alternate mfr.)
BTW, auto voltage control mode cannot be used to control taps due to generation on both sides of the xfmrs.

I would recommend to you two companies.
www.reinhausen.com with Tapcon240/260
and www.a-eberle.de with EG Sys.
Both of them are great devices.
Good Luck.

Devices are very friendly, first one I set up 90% without reading the manuals.

It may be like this in theory and practice, but in real life it is completely different.

Don't forget to order the remote position indicator in the tap-changer motor drive units (usually BCD code or 4-20 mA, check it in the AVR manual). Check if you need one AVR per transformer or if you want to control several transformers with the same AVR. Check what kind of interface do you want between AVR and the SCADA system (none, RS232, ...). There are a lot of issues that you must clarify before choosing the AVR.
