How to Coordinate Transformer Primary-Side Fuses with Feeder Reclosers Using Coordinaide
How to Coordinate Transformer Primary-Side Fuses with Feeder Reclosers Using Coordinaide™ — The S&C Protection and Coordination Assistant
This series of articles explains how to coordinate transformer primary-side fuses with a secondary-side automatic circuit recloser, such as in a utility substation. In Part I, we use the “conservative” coordination method, which ignores the effects of fuse cooling during the reclosing time intervals (contacts open) of the recloser. Part II repeats the exercise using the more precise “Cooling Factor” coordination method. Future articles will address source-side recloser/load-side fuse applications.
