Definition
- Noun:
- An instrument for indicating synchronization: A device that shows whether two periodic motions or alternating currents are in phase (occurring at the same time and rate). It visually indicates if the cycles are synchronous.
- A pilot's instrument: Specifically, an instrument in multi-engine aircraft that enables the pilot to synchronize the rotational speeds of the propellers.
Usage
- The synchronoscope is used in electrical engineering to check the phase relationship between two alternating current sources before connecting them.
- In aviation, a pilot uses the synchronoscope to adjust engine RPMs so the propellers turn at the same speed, reducing vibration and noise.
Examples
- Noun:
- The engineer used a synchronoscope to ensure the generator was in phase with the grid before closing the circuit breaker.
- A steady needle on the synchronoscope indicates the propellers are perfectly synchronized.
Advanced Usage
- "To bring into synchronism using a synchronoscope": The process of adjusting the speed or phase of one system to match another, guided by the instrument's reading.
- The technician brought the standby generator online by carefully watching the synchronoscope.
Variants and Related Words
- Synchroscope (n): An alternative spelling and the more common form of the word "synchronoscope". It has the same meaning.
- The control panel featured a large synchroscope for monitoring the generators.
Synonyms
- Phase sequence indicator: A device with a similar function for checking the order of phases in a polyphase electrical system.
- Sync indicator: A general term for any instrument that shows synchronization status.
Related Technical Terms
- Synchronism (n): The state of being synchronous, occurring at the same time and rate.
- The synchronoscope confirmed the synchronism of the two waveforms.
- Synchronize (v): To cause to occur or operate at the same time or rate.
- The pilot used the instrument to synchronize the engines.
Noun
- an instrument that indicates whether two periodic motions are synchronous (especially an instrument that enables a pilot to synchronize the propellers of a plane that has two or more engines)
