In synchronous generator, coil span factor is defined as ______.
1
Ratio of the actual voltage obtained to the possible voltage if all the coils of a polar group were concentrated in a single slot.
2
Ratio of phasor sum of coil voltages per phase to arithmetic sum of coil voltages per phase.
3
Ratio of the voltage generated in full coil to the voltage generated in short-pitch coil.
4
Ratio of the voltage generated in short-pitch coil to the voltage generated in full pitch coil.
