synchroscope sentence in Hindi

Examples

1. For most systems, synchroscopes are connected through voltage transformers to reduce the machine voltage to around 120 volts to operate the instruments.
2. Since most synchroscopes are connected only to a single phase of the two systems, they cannot assure that the phase sequence is correct.
3. As the frequency of the generator nears that of the grid, the synchroscope needle slows down and when the frequencies match, the needle stops rotating.
4. In a Weston pattern synchroscope, the moving element is not free to rotate continuously and oscillates back and forth slowly as the two sources are brought into synchronism.
5. In some power plants, a set of lamps may be connected between the generator and system busses ( or between the instrument transformers connected to those busses ) as a backup to the synchroscope instrument.
6. As a pilot aid to manually synchronizing the propellers, some twins have a small gauge called a synchroscope mounted in or by the tachometer ( s ) with a propeller symbol on a disk that spins.
7. There may also be controls for the supply of electricity to the switchboard, coming from a generator or bank of electrical generators, especially frequency control of AC power and load sharing controls, plus gauges showing frequency and perhaps a synchroscope.
8. Depending on the application and the circuit design, the breaker is closed when the synchroscope is pointing at approximately 5 minutes to noon, while traveling slowly in the fast direction, to allow the incoming generator to come onto the grid as a source.
9. If the generator is turning at a lower frequency than the grid, the synchroscope needle rotates continually in the direction ( usually counterclockwise ) marked " slow " or " lag " on the dial to indicate that the generator is running slower than, or lagging behind, the grid.
10. The angle between the systems is zero when the synchroscope needle is pointing directly to the line in between the " slow " and " fast " markings on the dial . ( In the picture example in this article, the zero-phase-angle position is straight upwards, at the twelve o'clock position .)
