What is the highest transmission voltage in India? I didnt get any exact answer.
@KARAD123 • 26 Dec, 2011 hope to get the answer to my question about tranmission voltage soon..
@Harshad Italiya • 26 Dec, 2011 I heard of HVDC transmission in India. Not sure about exact figure. Get information about HVDC in India.
@Suresh Manickam • 26 Dec, 2011 10,000 volts in main stream and 12-220,240 V in down stream.
@lal • 27 Dec, 2011 I remember reading that very long distance AC transmission voltages in India are 110kV and 230kV.

Edit : I figured out the above statement is presently not true and it is 765kV now.
@insane.nick • 27 Dec, 2011 hi KARAD
The highest transmission volatage in India is 765kV ac. The highest voltage in the case of DC transmission is +/- 600 kV.

ok... i guess even i read d same sumwhere.. thanks...
@KARAD123 • 27 Dec, 2011 thanks every1...
the teacher in my college asked us an question... which type of circuit is present in radios and televisions? ac or dc? I'm not sure about its answer... can any1 help?

Why not try to find answer on your own 😀

i didnt get a proper answer... thats y i asked....
@Suresh Manickam • 27 Dec, 2011 In both radio and TV, DC is used. to explain clearly contact me.

Why can't everything be discussed here? Explain what you've to explain here. Larger audience will benefit.
@Suresh Manickam • 27 Dec, 2011 Its too large post here.

Hi KARAD 123 you think you are so smart ...
excuse me... wat did i say? i just asked a doubt?
@durga ch • 31 Dec, 2011 @ All, please be clear and appropriate in your comments

@narayana murthy • 31 Dec, 2011 actually transmission from generating station is 400kv and in between there are about many step down or step up's hope i am clear in dc there is around 1000kv because it has to travel long distance

Hi KARAD 123 you think you are so smart ...
That was inappropriate.
@insane.nick • 05 Jan, 2012 hey admin and KARAD 123 ehen i was give you the correct answer then you share this post..
ok... i guess even i read d same sumwhere.. thanks...
then i was share this ...
Hi KARAD 123 you think you are so smart ...
okkkkkkkkk if you think i am wrong then i am sorry..............

the teacher in my college asked us an question... which type of circuit is present in radios and televisions? ac or dc? I'm not sure about its answer... can any1 help?
I think its based on ac circuits ,because radios & televisions based on the principle frequency .
frequency concept is only on an ac circuits.
@akpower • 15 Jan, 2012 • 3 likes Hi Karad123,
Exact answers to your queries are
1]Transmission voltage in India (highest) is 750KV AC and these lines are erected by Power Grid Corporation for interstate connections throughout India. However work on 800KV is also in progress.
2] DC transmission voltage (highest) in India is 600KV .This has restriction due to conversion i.e. AC/DC & inversion i.e. DC/AC for bulk power transmission.
3] Radio circuits use both. AC & DC.When AC supply is available ,the instruments(rectifier) convert AC to DC from 230volts to 6 volts for operating the other electronic circuits namely,amplifiers, converters,mixers etc.Since all semiconductors require only small DC voltage to drive them.
Hope it satisfies your query.

sure.... listen, a RLC circuit is used in radio and television to catch a proper frequency for visulisation as well as audio. at last both signals are synchronised. this is the working. RLC circuit works in dc so circuit is dc but creat oscillations like ac.
@SHRIKANT CRAZY • 06 Feb, 2012 hi karad 123
hey.......i don't know how much you are benefiting from your questions but i'm very much glad to know this type of interseting questions. thank you very much.........
@jarpala venkates • 04 Aug, 2015 thank you for giving this valuable information.
@Ganeshkumar.R • 08 Sep, 2015 Thankyou for valuable qes and answer I request to post more information
@alok raj • 17 Sep, 2015 nice to have such intresting queries.
The Generator terminal voltage is stepped up by the power station transformer to a higher voltage (115 kV to 765 kvAC, varying by the transmission system and by country) for transmission over long distances.
IN dc its up to 600kv.
@Bijay Krishna Nandi • 29 Sep, 2015 See as per the question- 800 kv HVDC transmission line is recently charged from Biswanath Chariali to Agra ( North East) first ever in India. However in AC transmission system it is 765KV generally both are erected and charged by PGCIL officials. I hope I have answered.

AC- transmision line --1200KV comissioned 6 moths back
traditional ac lines will be in the range of 132KV,220KV,765KV
132KV lines are majorly laid by the state governaments
220KV by power grid used to connect load centres from generation points
765Kv-1200Kv for high power transmission
DC-line--800v, for power transmission between load dispatch centres but not to load points
25KV single phase for railway lines

1200kV testing substation is at Bina In Madhyapradhesh not for transmission.
