Synchroscope is used to check _________.a)Frequency differenceb)Phase ...

Concept:

Synchroscopes are instruments that show the relative frequency (speed) difference and the phase angle between the machine to be synchronized and the system voltage.

The synchroscope works based on AC motor in principle. It has two poles connected across any two phases (say red and yellow) of the incoming machine. The armature windings are supplied from the similar two phases (red and yellow) in the switch board bus - bars.
Synchronization of alternator means connecting an alternator into the grid in parallel with many other alternators, that is in a live system of constant voltage and constant frequency.
Before connecting an alternator into the grid, the following conditions must be satisfied:
Equal voltage: The terminal voltage of incoming alternator must be equal to the bus-bar voltage.
Same frequency: The frequency of generated voltage must be equal to the frequency of the bus-bar voltage.
Phase sequence: The phase sequence of the three phases of alternator must be similar to that of the grid or busbars. Phase angle: The phase angle between the generated voltage and the voltage of the grid must be zero.
The first condition of voltage equality can be satisfied by a voltmeter. To satisfy the conditions of equal frequency and identical phases, one of the following two methods can be used: Synchronization using incandescent lamp Synchronization using synchroscope
