| 1. | Synchroscopes have a damping vane to smooth out vibration of the moving system.
|
| 2. | The cross-coil synchroscope somewhat resembles a wound-field induction motor.
|
| 3. | Synchroscopes measure and display the frequency difference and phase angle between two power systems.
|
| 4. | The synchroscope is connected to the power grid and to the generator being started.
|
| 5. | Synchroscopes are electrodynamic instruments, which rely on the interaction of magnetic fields to rotate a pointer.
|
| 6. | Iwatsu named it Synchroscope, and the first model was delivered to the Ministry of Defense in 1954.
|
| 7. | Synchroscopes operate only over a limited range of frequencies, a few per cent above and below the system nominal frequency.
|
| 8. | Iwatsu's Synchroscope continued to evolve in response to new demands, such as larger CRTs and higher frequency ranges.
|
| 9. | A polarized-vane synchroscope has a field winding with a phase-shifting network arranged to produce a rotating magnetic field.
|
| 10. | The position ( as opposed to rotation ) of the needle on a synchroscope indicates the phase angle between the two systems.
