why transmission line 11Kv OR 33KV,66Kv not in 10kv 20kv?
Answer Posted / anurag agrawal
The Basic Idea behind a desired transmission voltage was still the form factor. In ancient times when we needed to use 10 kV at destination, simply multiplied the form factor to it Say 1.11X10=1.11 =11KV aprox.(we had taken 10% losses as standard thumb rule) similarily for 30 & 60 KV.
Form Factor = RMS voltage/Average Voltage For AC sine wave Form Factor is 1.11.
Now a days when, we have voltage correction systems, powerfactor improving capacitors, which can boost/correct volatge to desired level, we are using the exact voltages like 400KV inspite of 444KV.
