1) Why distributiion system decided 11 kv, 33 kv, 66 kv,
132 kv, 220 kv, 400 kv,
2) In 3 Phase line terminal of capacitor, why used for
power factor improvement.
3) Why used rating KVA in transformer?
Answer / simon
<1>11KV=11000V (Max V to b produced in india).Hence
11*1=11kv
11*2=22kv
11*3=33kv.
<2> The cheapest mode to improve P.f is using bank of cap (series or para).
<3>For that try to understand wattful & wattless components.
