FUSE SELECTION
For a detailed explanation on selecting the appropriate backup current limiting fuse for a given
application, please refer to Hi-Tech Fuses Application Bulletin FS-10. For a quicker method of
selecting the proper 38kV Trans-Guard OS Shorty fuse for applications involving coordination with
ABB 34.5kV under-oil weak link expulsion fuses please refer to the following table.
ABB 34.5kV Protective Links (345B995G__) & 38kV Trans-Guard OS Shorty Fuses
Note:
Backup fuses are selected to melt only on internal transformer faults, where
transformer impedance is equal to, or greater than, the value given. For transformers
having lower impedances, consult the factory.
