Consultancy surching reasons for failures
Because fuses are rated break points and not wear and tear elements, there are of course many plants without any failure over years or even decades. If nevertheless a failure occurs after years, you want to know, how this could happen. Some reasons can be diagnosed by the status of the fuse. Even if the body of the fuse remained undamaged, certain conclusions can be drawn by the status of the fuse element. But first of all we have to clear some questions here too.
Have been damaged the fuses and the semiconductors?
Have been damaged only the semiconductors, while the fuses remained undamaged?
Has been burst the fuse body?
Were there traces of overheating in the fuse holder?
What kind of cross-sections had been displaced?
What kind of harmonics increased the rated current?
