HOW TO COORDINATE TRANSFORMER PRIMARY-SIDE FUSES WITH FEEDER RECLOSERS

摘要

In part Ⅰ, we explain how to coordinate transformer primary-side fuses with a secondary-side automatic circuit recloser, such as in a utility substation. We'll use the "conservative" coordination method, which ignores the effects of fuse cooling during the reclosing time intervals (contacts open) of the recloser.
