These were often driven by a separate electromagnet or motor,which allowed the interruption rate and"dwell" time to be adjusted separately from the primary current.
In powerful coils the high primary current created arcs at the interrupter contacts which quickly destroyed the contacts.
The primary magnetic field B→( r→){\displaystyle{\vec{B}}\left({\vec{r}}\right)} can be produced by a permanent magnet or a primary current J→( r→){\displaystyle{\vec{J}}\left({\vec{r}}\right)} see Fig. 1.
Primary current injection test set adopts ARM Chip to control its output process and large capacity of toroidal transformers.
If the secondary current x N is exactly the same as the primary current, the two magnetic fields cancel each other in the toroid.
