Question & Answers
*******************
Q). What about 400kV, 765kv transmission voltages?
A). trans line drop is not just 10% but we cannot exactly say the voltage drop as they changes proportional to the current and current value is not constant. so our scientists took some decent number which is 10%. But recently, we are going for higher voltages through advanced FACTS devices (where voltage drops will be compensated) hence this 10% is not valid for 765kV and further.
Q). Is same 10% extra rule is applied to modern high voltage also?
A). No, for modern high voltages (400kV, 765kV or higher) this 10% voltage drop is not applied, as now a days with the help of FACTS device we can compensate these drops and maintain the required voltage profile. So for modern high voltages this 10% rule is not taken into account.
Q). Then why the transformer voltages are rated at 11kV/440V or 33kV/11kV and so on and also on the board of any substation are written as 33kV/11kV Substation etc... Why?
A) if the line is operating at no load then there will not be any voltage drop hence we will get full 110% voltage so the transformers must be rated at full (110%) that is 33kV or 11kV or 440V.
Q). why only 10 % extra supplied by them...?...can it less or more?
A). You are absolutely correct, trans line drop is not just 10% but we cannot exactly say the voltage drop as they changes proportional to the current and current value is not constant. so our scientists took some decent number which is 10%. But recently, we are going for higher voltages through advanced FACTS devices (where voltage drops will be compensated) hence this 10% is not valid for 765kV and further.
Q). how did u choose 10kv,20kv,30kv etc at the receiving end?
A). these voltages (10kV, 20kV, 30kV......) are chosen based on the transmission distance.
Q). Why not 44kV and 55kV voltage levels??
A). Yes we can make 44, 55, 77.... like that. But there is no point in having all levels of voltages for every transmission distance.
Earlier days 11, 22, 33, 66, 132, etc.. are considered based on the transmission distances and these levels are found satisfactory for different transmission distances.
We can’t keep on designing each voltage level (cost considerations)
Q). Why we are not generating and transmitting power in at the 1kv, 2kv
A). Earlier we don't have the concept of distributed generation system, so power stations are far away from the living places, hence to transmit power for such a long distance small voltages will not be efficient. We should go for as high voltages as possible but we can even generate direct 220kV also from generator (due to the insulation and other limitations of generator) hence we generate from 10kV to 25kV. But , now a days we do have a generating station with 1kV or 2kV in that range (distributed generation, wind, solar and etc)

[@tarunpathak01]

महाराज, T.L. losses depends on *Type of load * load value * length of T. L. *Voltage levels So can you assume losses are always 10%? * Transmitting voltage is multiple of 11kV is because of design of elec. Equipment which can easily do their functions at these voltage levels easily.

[@ThePiSquareAcademy]

Please check the description for the answer to your question

[@msai-rj2op]

How you can prove your way is correct​@@ThePiSquareAcademy

[@unknownfactstech3995]

I have a doubt in this why you select that to send 10kv,20kv,30kv why not 40kv,50kv,70kv..etc

[@ThePiSquareAcademy]

join tomorrow's live session to get an instant answer to your question check our facebook page for more details

[@surajsrivastava8482]

The voltage ratings are provided for the load itself. 11KV system means the power system is delivering at 11KV to load. In order to compensate line losses we have to increase voltage beyond 11KV at sending end.

[@subhajitbasak2692]

Sir, your explanation is very logical....and very basic....but I cannot digest from where this requirement of 10kV, 20kV, 60kV, 120kV at receiving end come??? and if we talk about Electrical load, say motors, we find 3.3kV, 6.6kV, 11kV motors.....rather than 3kV , 6kV or 10kV.. I hope i could explain my doubt

[@gauravsaluja2381]

Subhajit Basak @ mera bhi same doubt h

[@gauravsaluja2381]

Subhajit Basak ye 10 kv k requirement kha h??

[@mdkhadse04]

i too hv same doubt

[@subhajitbasak2692]

main v to uploader se wohi question kar raha hu.....industry me industrial or distribution level pe 10/20/30..../60/70 kV etc ka requirement kab se aane laga??

[@elamsraj1595]

I think 10kv never heard in my area . In substation also 11 kv /415 v , 33kv/ 11kv , 132/ 66kv , are using in many areas . But for your questions , all drives voltage like 3.3 kv , 600v , can be obtained by rectifier and then inverter . If you are seeing in industries u will come to know all these things

[@mohammadrizwanqureshy7142]

sir if u r right then what is the role of ferranti effect. I went to 132kv/33kv/11kv substation where I saw. receiving voltage is 135 kv instead of 132 kv. plz reply

[@ThePiSquareAcademy]

It is one case in transmission line which occurs when the line is lightly loaded or no loaded. So it has no role in choosing the voltage levels. Ferranti effect places a key role in designing the transmission lines.

[@Bindugiragani]

MOHAMMAD RIZWAN QURESHY ferranti effect means receving voltage greater than sending voltage at no load or lightly loaded condition.so u give 132 kv at sending end we get more than 132 kv due to ferranti effect

[@elamsraj1595]

Then surge impedance

[@psrelectricalzonetelugu]

MOHAMMAD RIZWAN QURESHY

[@soumyadipmishra7543]

Sir, Then why the transformer voltages are rated at 11kV/440V or 33kV/11kV and so on and also on the board of any substation are written as 33kV/11kV Substation etc... Why?

[@ThePiSquareAcademy]

Dear Mishra, if the line is operating at no load then there will not be any voltage drop hence we will get full 110% voltage so the transformers must be rated at full (110%) that is 33kV or 11kV or 440V.

[@mohammadsajid5896]

PiSquare Academy bro no load losses pata hai kya tume.

[@nitinsourabh4003]

PiSquare Academy Sir, but you were telling that the 10% extra voltage is for transmission line voltage drop. So now whether the line is loaded or unloaded it doesn't make any impact on voltage drop no! And If the line is unloaded also there exists voltage drop in transmission line na?

[@rarichanjoseph7909]

Nitin Sourabh no load, no losses!!!

[@bjtaudio]

The the 10% rule was originally applied to get the 11 22 33 66Kv etc distribution system voltages, It not really used anyway, It's actually 11kV to the load not at the feeding end, voltage drops are typically only a few percent not a massive 10%...The 10% figure was an amount agreed on and what was practical at the time. System voltage for a zone is chosen based on the size of the load and distance, future growth allowances, cost, and compatibility with existing systems.

[@JaswanthDaniel]

My understanding according to form factor is a machine is generally designed for voltages of maximum amplitude of 10KV or 30KV or so. From this, taking sinusoidal form factor as 1.11, we get 11KV or 33KV. Please tell if I'm wrong.

[@ThePiSquareAcademy]

Dear Jaswanth, watch the video once again, already form factor is proved wrong. Watch again for more clarification.

[@bjtaudio]

Don't forget these standards were developed many decades ago, and has become widely adopted. As parts and transformers are ready to go on the shelf, it make sense to use them.

[@electricalsmartereveryday1013]

Very nice 🎉

[@sharethestuff3755]

sir this logic is not applied for 765kv transmission line to get 700kv at the receiving end.

[@ThePiSquareAcademy]

Answer is given in the Video Description Please read the description (FAQs). Thank you.

[@chaisrav225medisetti]

If so the concept then we all are designing transformer for 11KV/415V but if transformer requires 11KV then we have to transmit more than 11 KV in line to reach to 11KV transformer but still line transmits only 11 KV. Otherwise transformer world be 10KV/415V. Is it right

[@sathishkumarg1979]

how to separate this kv levels.any standard is there or not?

[@rajurosy]

Dear Sir !! Really much appreciated for providing this information. I have some questions for You and hope You will clarify them. Why You have chosen only 10% extra though transmission line drop depends on both resistance and length of transmission line ? I haven't seen any cases with receiving end voltages are just 10KV , 20kv and so on .. Our ring distribution system receiving end voltage is 11KV ? According to Your approach ,Does sending end voltage is 13.2 KV ? Please clarify me..

[@ThePiSquareAcademy]

Answer is given in the Video Description Please read the description (FAQs). Thank you.

[@Venu_Gopal72]

sir I have small doubt. why we are using 11kv, 33kv, 66kv and 132kv, and why not we r using 22kv,44kv 55kv, 100kv?

[@rabinarayanpanda6280]

If single phase is 220v then how much will be 2 phase and how much will be 3 please?

[@prasadaraokarri6465]

sir actually our load designed for 220V not 200V . and at 400kV and 765 KV your logic does't work

[@abhijitha8867]

It is not the matter of 10% loss and all. It is just a standard convention followed throughout for the ease of interconnecting lines to the existing sytem. Simply saying, there is no technical reason for choosing these ratings.

[@darampavanreddy3604]

Dear sir, Why we r not generating and transmitting power in at the 1kv, 2kv,..etc Why we r going for directly 11kv...

[@ThePiSquareAcademy]

Earlier we don't have the concept of distributed generation system, so power stations are far away from the living places, hence to transmit power for such a long distance small voltages will not be efficient.

sir ,why generate standard in india is of 3.3,6.6 and 11 kv.

[@NumanKhalidKhalidMehmood]

Why they only want to transmit 10 KV, 20 kv, 30 kv and 60 kv only at receiving end? Why not others ratings like 15 kv, 25 kv, 34 kv or any other random rating?

[@cmsingh8966]

In case of 765kv transmission voltage.. what is the value behind that overall losses it becomes 765 kv

[@ThePiSquareAcademy]

trans line drop is not just 10% but we cannot exactly say the voltage drop as they changes proportional to the current and current value is not constant. so our scientists took some decent number which is 10%. But recently, we are going for higher voltages through advanced FACTS devices (where voltage drops will be compensated) hence this 10% is not valid for 765kV and further.

[@philip4567890philip]

first installation they used 11kv,22kv,33kv,66kvetc are based on optimum level voltage (ie) mainly cost consideration. for example if you need 50kv means you have to design 11kv/50kv transformer. thats why 11kv 22kv 33kv 66kv 132 kv. these are standard rating. now another one standard rating is come into the picture that is 765kv. if you design the transformer for 1000 kv then your rating will also be included in the standard rating.

Sir I have a question. Why CT rating is 1000/1 500/1 100/5 500/5 etc not in any other ratings? pls reply

[@ThePiSquareAcademy]

As we know CTs are used for current measurement, keep this in your mind and understand below points to understand the answer. 1. CTs are required for the high currents, in the order of kA; 2.The rated secondary current is normally "STANDARDIZED" at 1 or 5 amperes (you please try to understand the the word standardized clearly); this standardization is done based on measurement and relaying ease. 3.We cannot make CTs for every operating current.

[@AjayKumar-hi6yd]

What about 765kv transmission line??? Can we apply the same logic?

[@ThePiSquareAcademy]

[@gauravgupta2470]

Ok Sir, But what about IEC standards, 10, 12,36 kv ,so where is 10% loss in other countries.

[@ThePiSquareAcademy]

Over time, certain voltage levels have become standardized and widely accepted within the industry. This standardization helps ensure interoperability, compatibility, and ease of maintenance across different electrical equipment and systems. But there is no such rule that everyone should obey them, but we loved that standardization so we are following. You also check video Q&A for more details.

[@ThePiSquareAcademy]

Dear Gokul, read the description for the answer

[@kiranvoodari5789]

Your answer fails to answer why generation voltages are generally 11kV and 33kV. Please clarify.

[@bjtaudio]

The 10% voltage drop is worst case thou. Its a voltage standard that was adopted and it stayed, a voltage drop of 10% is truly a massive loss of power thou, its typically just a few percent at peak load in most parts of a transmission network. The same 10% applies between point of supply and plug-gable LV appliance too. Where up to 5% voltage drop at full load in low voltage building wiring by law, and up to another 5% allowing for further voltage drop in the extension cord to an appliance on the customer end. Also voltage drop in transmission is due to transformer impedance, this i compensated with a tap changer, the high impedance is to keep the fault current down.

[@targetwithmaheshkushwaha]

Sir as we all know we are generating 11kv,22kv,33kv....etc .but according to you we are generating 10kv ,20kv,30kv...etc. and thereafter we transmitted it by increasing 10%. So what is the answer if in any intervier asked generating power ratings then can I say we are generating 10kv,20kv....?? Plz clear my doubt becoz 1st ever I know about 10kv,20kv..........etc and it's really confused me there is no such proof in any text book . Thanks

[@ThePiSquareAcademy]

Answer is given in the Video Description Please read the description (FAQs). Thank you.

[@vineethreddyvangala8413]

Hi sir, you stated that, 110% of voltage level is increased and transmitted. Actually, I have worked in one of the substation. I observed the readings of incoming line voltmeter, it reads more than the rated voltage of primary of PTR, the PTR is operating at 80% of its rated load. Then, if you say 110% of voltage level is increased, it may show a slow deposition of charge in the insulation and may effect it's dielectric strength. Please, say me how they avoid, that effect. Thank you.

[@IrfanMujawar]

Good explanation. Voltage drop also take place in inductor IXL. I also think this is also the standardization that is followed in India.

[@chandramoulihm]

I don’t think this is right, If you are connecting a load with in 2 km near to generation station then they will receive 10.9 kv instead of 10 because of less voltage drop. And also for long transmission lines due to Ferranti effect you will receive 12 kv instead of 10. So this logic doesn’t works. May be because of predesigned equipment which works on 11kv, 22kv, 33kv they are supplying the same voltage. This question is just a myth their is no pattern behind it, if you consider like that why they are transferring 400 kv instead of 440kv or 765kv which is not multiple of 11.

These are the voltage levels used in recent times, so recently we use FACTS devices to compensate the voltage drops so, voltage drop is taken care by FACTS devices hence we don't consider 10%.

[@harishpodagatla6526]

in 11kv 10% voltage drop this is your answer, i cant agree because nearest to the power station less voltage drop or no losses then nearest to the t/f 11kv and away from the t/f 10kv

[@Lucifermorningstar69923]

sir whats the ans of 11/66 kv = how much kva?

[@satyanarainu]

Bro.. what about 765 KV and 1200 KV??

[@ThePiSquareAcademy]

Answer is given in the Video Description Please read the description (FAQs). Thank you.

[@khagapatinayak3125]

What if I want 25 kv

[@Deepakkumar-qc8pw]

add more this type video

[@nagarajusiva2082]

Why u are considering 10%only extra .What is the perfect reason is?

[@entertainmentinformative9896]

if we send 11 kv we can get 11kv in other side by steping transformer tap

From power plants how much of power is produce by turbine

[@lixycarrillo9783]

Excellent...thank you!

[@lindokuhlexaba1134]

Hey carrillo

[@kanishkapaliwal9509]

in copper we can change the voltage

[@ThePiSquareAcademy]

Sorry, i couldn't get the question clearly, please elaborate it.

[@SachinVerma-oe3fs]

sir plzz make few videos on induction motors,relays(electronics realy like DMPR,EOCR,Numerical relay),contactors,CB,load cells ,and few videos on chopper SCR dat are generally used in industrial purpose. Ty sir for making these kind of conceptual videos...ty so much sir

[@ThePiSquareAcademy]

why we not consider the voltage level of 40 Kv, 50Kv, 70kv ......and so on

[@ThePiSquareAcademy]

Answer is given in the Video Description Please read the description (FAQs). Thank you.

[@alok171]

Can you mention transmission regulations rule under which the generating company has to supply 10% extra over nominal generated voltage

[@shaikramthu1036]

Tks anna

[@talariupender9772]

As the transmission voltages are increasing why 10 percentage excess voltage is maintained constant. Why it shouldn't be varied according to voltage level

[@ThePiSquareAcademy]

You may please check the Q&A Session in this video description for more details which might answer your question.

[@bijoynag8815]

if the logic as simple as you said, then why should we transmitted 400 KV?

[@Pariharnawab]

Thnq u very much sir for making valuable video
