Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- Lamps bright synchronization preferred to lamps dark because it gives sharper and more accurate synchronization.
- Synchronizing bright and is generally preferred because it is found to be easier to determine when a lamp is at full brilliancy than when it is absolutely Dark (current less), for it may be carrying quite a substantial current without reddening the filament. The lamp may even become dark with a considerable difference in voltage.
The ideal synchronizing device should perform three distinct functions:
- It should indicate whether the incoming machine is running too fast or too slow.
- It should indicate the same amount of phase difference.
- It should indicate the exact moment of phase coincidence or synchronism.
