Hi all,
As I learned for synchronization, their are five factors to be considered. Should have:
Equal line voltage
Same frequency
Phase angle
<b>phase sequence</b>
Waveform.
Waveform is fixed by the construction of generator. And when we connect generator to grid, do we need to consider the <b>phase sequence</b> or <b>phase rotation</b>?
Can we separately identify R-Y-B (Red-Yellow-Blue) in 3 phase waveform?
Pick a phase and named it as phase R (Red) and relative to that can identify phase Y (lead 120 degrees in balanced 3 phase waveform) and phase B (lag 120 degrees in balanced 3 phase waveform). This can be done using phase rotation meter.
So my Question is how to identify the phase R (red) in a electric power system? I saw in internet that their are separate instrument to identify phase sequence and phase rotation.
I thought that phase rotation is enough to connect a generator to grid for synchronization.
can some one please explain it?
