Requirements

•Similar (practically identical Z%

•Solid high-side bus (no separate sources)

•Comparable step voltages and ranges (but some differences may be

tolerable

•Provisions for LDC

•Same winding ratios

•Same MVA rating (ratio correcting CTs may be used)

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

• 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
