Bcoz the form factor is multipl of 1.11 for sinsoidal wave(AC)
| Is This Answer Correct ? | 9 Yes | 0 No |
Answer / tharanidharan a
1.1 is form factor of a Sine wave...hence ac voltage being
a sine wave holds Form Factor of 1.1, which
is the ratio of rms value to average value of alternating
current.so generation of ac voltage is in multiple of 11,
like 11kv,33kv,44kv,66kv etc
