Question

A 3-phase, 50 Hz, 16 pole generator with connected winding has 144 slots with 10 conductors per slot. The flux/pole of 24.8 mWb is sinusoidally distributed. If coil is full pitched, then line voltage is _______V.

• A. 2288.635

Answer 1

The correct option is A 2288.635
Given,
Number of phases = 3
Frequency, f = 50 Hz,
No. of poles, P = 6
No. of slots = 144

$\text{Turns per phase,}{N}_P=\frac{144\times 10}{2\times 3}=240$

$\text{The rms voltage per phase}=4.44f\varphi N_P$

$=4.44\times 50\times 24.8\times {10}^{-3}\times 240$

$=1321.344V$

$\therefore \text{Line voltage}=\sqrt{3}\times 1321.344$

$=2288.635V$
