Overview
•Older analog methods required relay logic
•Master-Follower actually the most common method used in rest of world
•Only the master regulates
• con ro ers nee pos ve pos on now e ge
•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
