| 1. | Some industrial customers require three-phase power at secondary voltages.
|
| 2. | Secondary voltages have influenced many of the differences in distribution systems.
|
| 3. | The potential of the secondary voltage now flips to negative in the following manner.
|
| 4. | Exceeding the secondary voltage may also degrade the accuracy of the transformer or even destroy it.
|
| 5. | The secondary voltage drops to zero.
|
| 6. | Higher secondary voltages, such as 480 volts, are sometimes required for commercial and industrial uses.
|
| 7. | How the heck does the upper half get energised for you tap off a stepped-up secondary voltage?
|
| 8. | :: : Yeah but in the transformer article it says the pimary current creates a secondary voltage by induction.
|
| 9. | The power losses are measured by means of a wattmeter method in which the primary current and secondary voltage are used.
|
| 10. | In the transformer article, it says that the flux in the core cuts the secondary winding to give secondary voltage.
