Reliable Protection for High Voltage Transformers
High voltage back-up fuse-links protect transformers by interrupting significant short-circuit currents before excessive thermal or mechanical stress can damage the transformer windings, switchgear or connected distribution equipment. They are normally coordinated with another protective device capable of clearing lower-level overload currents.
The Mersen N1000098 combines dependable fault protection with an integrated striker that can operate compatible switchgear when the fuse interrupts a fault. This helps isolate the affected circuit, improve fault indication and support safer maintenance within medium voltage installations.
Typical Applications
- Medium voltage transformer protection.
- High voltage switchgear assemblies.
- Transformer substations.
- Industrial power distribution systems.
- Utility distribution equipment.
- Ring main units and compact substations.
- OEM transformer controlgear.
- Commercial and industrial electrical infrastructure.
