TAPCON® 250 Digital Master-Follower Scheme

Overview•Older analog methods required relay logic

•Master-Follower actually the most common method used in rest of world

•Only the master regulates

All t ll d iti iti k l d•All controllers need positive position knowledge

•Perfect and actually preferred for applications where each transformer naturally carries the load evenly on the same tap position.

•Same Z%

•Same Vector Groups

•Same # of Taps

•Same step voltage
