We say that if voltage in a power system is increased,for a
constant power the current will decrease (by P=VI).
isn't this in disagreement with the ohms law(I propotional
V;resistant const.).Since the resistance of transmission
lines remains constant,shouldn't inc in voltage cause inc in
current across the transmission line?
I have read many articles across the net but still couldn't
this figure this out. :(
Guyz plz assist me with dis..:)..

Answer / j k sahoo
Due to the demand of power line current will increase,
according to P=VI, whereas voltage will remain constant by
maintaining the AVR.

Answer / pandeyrahul
load decides current value but to do P constt we have to
change v by kvar reactive power, low kvar can reasult
unablity to transmit a constt voltage through long
transmission line

what is rocking arrangement in arc heating
Three set (each phase contain 2 cable of 400 mmsq CU XLPE AWA) of single core cables are connected to 11 KV motor of 14 MW & the switch gear supplay is taken from 11kv feeder & this supplay taken from 275 KV substation. Problem is one pair cable(L3- 2 cable ) getting very hot & gland melted and damaged in switch gear side. the other two cable haven't any more hot(ambient temp only & L3 haveing 95- 100 Degree C. The same problem happened in 275 KV substation switch gear side also where the supply taken for 11 kv switch gear. But here L2 phese cable had problem. Why it is happening like this?. The cable having temperature different at different location from gland side inthe case of 11KV feeder of 275 kv substation. why ?
