S&C - Model Fault Tamer -Fuse Limiter
S&C Fault Tamer combines the functionality of a conventional fuse cutout and a backup current-limiting fuse in one powerful, easy-to-install package for the protection of new or existing overhead pole-top transformers through 25 kV. Fault Tamer addresses the critical issues facing protection engineers today. Fault Tamer is manufactured in accordance with a quality system certified to ISO9001:2000.
For outdoor distribution, 15 kV through 25 kV
Combines the functionality of a conventional fuse cutout and a backup current-limiting fuse in one powerful, easy-to-install package
Fault Tamer provides these features and benefits over traditional fuse cutouts, or cutouts used in combination with backup current-limiting fuses.
Improved Transformer Protection
- Ideally suited for protecting single- or three-phase transformers through
- 100 kVA single-phase at 15 kV
- 167 kVA single-phase at 25 kV
- Excellent continuous, hot-load pickup, and cold-load pickup capabilities.
- High surge withstand capability. Allows arrester to be mounted on transformer tank without increasing the chance of nuisance operations due to lightning.
Energy Limitation
- Minimizes equipment damage
- Reduces chances of catastrophic transformer failure from internal high-current faults.
- Minimizes bushing and tank damage due to external primary faults.
- Improves service continuity
- Provides complete coordination with upstream lateral fuses.
- Provides complete coordination with substation instantaneous relay settings.
- Enhances power quality
- Minimizes voltage dips that can cause sensitive electronic equipment to shut down.
Operational Characteristics
- Dropout action.
- No parts expelled during circuit interruption.
- Complies with Australian Spark Production Standard AS 1033.1-1990. Ideal for installation in areas prone to grass fires.
Handling Characteristics
- Easy to install/remove using extendo stick. No climbing or bucket truck needed to re-fuse . . . unlike conventional backup current-limiting fuses.
- Retrofits into all vintages of S&C Type XS Fuse Cutouts.
- Operable with Loadbuster®, S&C’s Portable Loadbreak Tool.
