Gourav sir >>>>>teachers in class
🙏🏻Ur efforts matters a lot
Thank you !!
It was quite helpful to understand the difference between these two giants of transmission. Thank you keep uploading videos like that.
Excellent Explanation Sir ⚡...HVDC is only used in Primary Transmission of power system.
Thanks
Nice explanation. Thank you. Even when two grids follow the same frequency standard the frequency stability of both is also very crucial. For bidirectional transmission in HVDC both converter stations will require Ac to DC and DC to AC converter. This is not a small cost but cost is always justified in any project.
Thank you for the great explanation.
hello sir ,
i watch ypur all video, Literally it is very very useful for clearing basic doubts and very good for basic knowledge . very very thank you.
Good explanation. Thanks very much 😊
You keep going man, you're doing great😊
Great stuff. Kudos 👍
Well done sir, very interesting and informative. As i watched I had several questions that you fully explained.
Good job thanks
Impressive knowledge such a beautiful and easy to understand all your fantastic educational valuable videos
Thanks and best regards ☕☕
What does the ink say on your right wrist? Just curious. Great discourse on this complex topic, sir!!!
Explanation is amazing sir 👌🏻🔥.
But I have doubt! In distribution side i heard about a terminology called "back feed or back feeding" and i do experience it. But u just mentioned in this video that hvac is unidirectional. Could u please explain me sir?
What source can I look up size of cable v frequency? i.e. the difference between DC/AC size cable for the same voltage?
Great class Sir. Kindly do a video on solar power generation, net metering and gross meterin
I thought that the break-even point was based on the infrastructure costs; but it seems like just the efficiency could make it worthwhile with that amount of power, IDK? Thanks, good video!
Infrastructure would count as well. Overall view is seen
Helpful
Sir,please make a video about VFD,Soft starters..
A very informative video.
However I have to dissagree with you about AC systems not being able to be bi directional. AC based grids regularly transmit power in different directions as demand and supply varies throughout the regions within which they operate. Indeed energy storage systems also make use of this ability. Whilst power producers - whether mechanical or inverter based - have to be syncronised accreos the grid, the direction of energy flow is controlled by varyation of the relative voltages between suppliers and consumers.
Could you explain about transposition tower in transmission line?
👍
Excellent explanation Sir,
But next video make on how to work Convertor station, what is valve hall in HVDC system and today which country is more installation HVDC transmission line.
SIR, can you provide the how much the initial installation price differs from HVAC TO HVDC.
Hm. A general talk with a "higher-lower" terminology doesn't help. I would like to understand, so some typical numbers would help. What are we talking about. And how would it be possible that for the DC transport there is no loss!? Every conductor has resistance. P=I^2 R. For AC transport, the frequency is quite low, so I don't expect the reactance due to inductance and capacitance to be high. Actually, both systems need to deal with the same resistance part. But both systems are high voltage to keep the current lower, as I said P=I^2 R, so we want to keep the current as low as possible. Every cable is heavy, so for AC, they build a cable in such a way that inside you have less conducted carrier, and outside the good condctive material for the skin effect. Maybe the HVDC has potential, but I would like to see the numbers, regardless of more complicated conversion for DC, just the transport per unit length. Cheers
Bro what do you believe are some top traits and tips to become a high earning hvac engineer in Aec construction industry working for air conditioning projects.. which books would help in this scenario..
Interesting video , But my question is if the original power supply was by a DC generator would it produce power using less horse power than an AC alternator system ?
sir, give video detailed video about distance relay
Please make video on battery charger.
It's hard to judge but I think the distance will be the best to judge from.
Certainly
Can we connect SVC to 220 KV system?
Cross-bonding and SLV (Sheath Voltage Limiter) earthing
Details me video banayo thora
Sir this one is very informative thank you.
Sir can you please do a video on the HVDC transmission line protection schemes as in the case of HVAC we are having inductance parameters for the use in relay 21 (backup protection), where as in HVDC only resistence is present.
And one more thing sir, why is HVAC transmission bidirectional power flow not possible, like the lines we use to send power can also be used to receive power back as if the power sending (export) is less than power recieving (import) we will be recieving power to the grid and vise versa , correct me if I'm wrong.
Thank you . I’ll try 👍🏻
I wonder why the losses in HVDC remains the same with increasing distance, can anyone enlighten me please? I'm thinking about the formula R=pL/A where the resistance is proportional to the distance. Or am I using the wrong equation here. Thanks.
I think he's talking about the "rate" of loss that is constant in HVDC. Which is right in line with what you mentioned, that is, the resistance is proportional to length. So, for each unit length of wire, the loss will be constant.
@@RajivLochanPanda oh yeah, I see. Thanks. He means the resistance in DC vs the impedance in AC.
Bro I have a doubt,Losses in DC is less then why not it used as transmission ,the high cost is the only reason for this
Isn't HVAC is also Bi-directional. When a powerplant needs backfeed it uses the same transmission line to start the power plant.
Same question, as solar panels also backfeed Into the grid through the same lines. Which made me second guess the statement that AC would be unidirectional.
Sir plz convert this video in hindi
Sir koi Group hai WhatsApp Ap ka?
No. But we do have a community on courses.theelectricalguy.in
Dc current voltage drop when it is go transmission lines the process not possible in America then many people used ac current, your explanation was wrong dc current must requires thick conductor when AMPS increased,I have a doubt about your class how can you transmit dc current using transfer, transfer only used for ac supply,if your connect dc supply to the transfermer how it achieve contraction and expension of core with flux and induced EMF it not possible in dc current because of it nope any cycle frequency then how it creates repulsion and extraction in the winding
Please answer questions I need your response it is helpful to me
Transformers only used for ac current to voltage and AMPS increase or decrease
HV AC or HVDC it does not matter it is utilitie talk you do not have to deal with it
it is only for transportation from electricity it is the same like talking about
walking on mars we know that 99,99 % of all people willl never walk there.
Can we connect SVC to 220 KV system?
