| 1. | When the primary current is suddenly interrupted, the magnetic field rapidly collapses.
|
| 2. | Its primary current use is for Zacatepec Siglo XXI ( 2014 present ).
|
| 3. | In a low-inductance coil, fewer primary turns are used, so primary current is higher.
|
| 4. | Then the primary current is turned on again, and the magnetic field opens the contacts again.
|
| 5. | Less flux means the inductance seen at the primary gets reduced so more primary current flows.
|
| 6. | In powerful coils the high primary current created arcs at the interrupter contacts which quickly destroyed the contacts.
|
| 7. | The relationship of the current reaction against the primary current is proportional to the number of turns against reaction:
|
| 8. | The power losses are measured by means of a wattmeter method in which the primary current and secondary voltage are used.
|
| 9. | The secondary voltage ( red, left ), is roughly proportional to the rate of change of primary current ( blue ).
|
| 10. | The conductor carrying the primary current is then passed through the ring; the CT's primary therefore consists of a single'turn '.
