Reliable Protection for High Voltage Transformers
High voltage back-up fuse-links protect transformers by rapidly limiting and interrupting severe short-circuit currents before excessive thermal or mechanical stress can damage transformer windings, switchgear or connected distribution equipment. Their current-limiting action also helps reduce the peak current and energy passed into a fault.
The Mersen Q1006103 combines dependable transformer protection with an integrated striker that can provide fault indication or operate compatible switching equipment. As a back-up fuse-link, it should be coordinated with suitable protective equipment capable of clearing lower-level overload currents.
Typical Applications
- Medium voltage transformer protection.
- High voltage switchgear assemblies.
- Transformer substations.
- Ring main units.
- Industrial power distribution systems.
- Utility distribution equipment.
- Renewable energy installations.
- OEM transformer controlgear.
