Current Limiting
Potential transformer (PT) fuses are current limiting fuses with high interrupting ratings designed for the protection of potential transformers
When applying fuses for the protection of transformers, the magnetizing current in-rush must be considered
The characteristics of the in-rush, which can be matched with a fuse time current curve
