Instrument(s) required to synchronize an alternator to the grid is/are:
Show Hint
- Voltmeter
- Wattmeter
- Synchroscope
- Stroboscope
The Correct Option is A, C
Solution and Explanation
- Voltage magnitude
- Frequency
- Phase sequence
- Phase angle
A voltmeter is used to match the voltage magnitude of the alternator with that of the grid.
A synchroscope indicates whether the alternator is running faster or slower than the grid and helps in matching the frequency and phase.
