Oil Immersed Current Sensing
|
 |
GENERALThe RTE® Oil-immersed current sensing weak link cartridge fuse is an internal, “weak link” expulsion fuse. It is designed for use in transformer oil or approved equivalent on the high voltage or primary side of distribution transformers. |
This cartridge fuse provides an economical means of fusing because it protects distribution systems from failed transformers, and also protects transformers from excessive overloads and fault conditions. Current sensing cartridge fuses can be used alone or combined in a two fuse protection system where high fault currents may be encountered. In a two-fuse system, the cartridge fuse is connected in series and coordinated with the primary
current-limiting fuse. This arrangement allows low current faults and overloads to be cleared by the internal cartridge fuse, while high current faults are cleared by the current-limiting fuse.
Oil Immersed Dual Sensing
|
 |
| GENERAL The RTE® oil-immersed dual sensing weak link cartridge fuse is an internal, “weak link” expulsion fuse, designed for use in transformer oil or approved equivalent on the high voltage or primary side of distribution transformers. It provides an economical means of fusing because it protects distribution systems from failed transformers, and also protects transformers from excessive overloads and fault conditions. Dual sensing links both internal fault currents and transformer fluid temperature. They will limit long-term transformer heating caused by overloads and high temperature environments. |

Dual sensing cartridge fuses can be used alone or combined in a twofuse protection system where high fault currents may be encountered. In a two-fuse system, the cartridge fuse is connected in series and coordinated
with the primary current-limiting fuse. This arrangement allows low current faults and overloads to be cleared by the internal cartridge fuse, while high-current-limiting faults are cleared by the current-limiting fuse.
