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

1. Inductor ndi yofupikitsa pakati pa kutembenuka, ndipo inductance ndi yaikulu kwambiri.

2. Gulu lozungulira la zida ndi lonyowa.

3. Gulu loyendetsa galimoto lathyoka.

4. Gawo la IGBT lasweka.

5. Zolakwika monga kuyatsa kwa thiransifoma zimayambitsa zochitika zambiri.
