Inter-Teknik – Distribution Transformer – Adapt Australia Integrating back-up current-limiting fuse-links in transformer tanks probably represents the most efficient use of HV fuses. There is one very simple rationale behind: "Fuses associated to trans-formers do not need to be replaced if properly selected." As fuses are only meant to protect the transformer tank from opening in case of catastrophic failure, these fuses will never ...
