High frequency induction hardening machine tool overcurrent: there are several situations in general overcurrent

1. I-inductor i-short-circuited phakathi kokujika, kwaye i-inductor inductance inkulu kakhulu.

2. Ibhodi yesekethe yezixhobo imanzi.

3. Ibhodi yokuqhuba yaphukile.

4. Imodyuli ye-IGBT yaphukile.

5. Iimpazamo ezifana nokutshiswa kwe-transformer kubangela i-overcurrent phenomenon.
