I'm really enjoying this channel for content and clarity. The videos don't seem nearly as long as they are and I don't get confused with TMI. So much to absorb, and what a great teacher! Greeting to all from Michigan, USA.

What source can I look up size of cable v frequency? i.e. the difference between DC/AC size cable for the same voltage?

Helpfull

Wish you also touched upon early detection of PD like using thermal imaging.

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

good explanation

You keep going man, you're doing great😊

Clear brother. .thanks

Well explained Switching over voltages

I don't inderstand how extra amps on a load could affect the voltage balance ! I thought that voltage between phases is fix and known and also voltage between each phase and neutral is also fix and known ! Thanks

Cross-bonding and SLV (Sheath Voltage Limiter) earthing Details me video banayo thora

SIR, can you provide the how much the initial installation price differs from HVAC TO HVDC.

Please make video on battery charger.

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 ?

220/30

sir you are sparking the mind what we want to digest. ok so creative idea.

Helpful.

In 11KV , I have seen no neutral, but before substation why there are 6 wires? And at distribution (step down) transformer, how the neutral line is introduced, please explain the connections

6:40 Neutral is needed in distribution system because it is not balanced=we can not control the load

Race is there conducting state and insulating state

5:10 Arcing medium is trying to regain its insulating properties

It can cause reigniting and rearcing

This TRV is more across the first pole to clear the

3:21 waveform n TRV depends on 4 factors 1) condition at which the contacts are separating ???? 2) Type of fault 3) Characterstics of Network connection ???? 4) switching arrangement

3:00 TRV has several times higher frequency than normal system voltage

2:33 each n/w develops a voltage simultaneously at the respective terminals of the interrupter

8:40 triple line fault is the severest fault a power system can witness (even though system is balanced before and after the fault)

Helpful, thanks!

8:52- Rating of Circuit Breaker is decided based on triple line fault

Helpful. Thank you.

sir, give video detailed video about distance relay

For become excellent engineer s with simply explanation by u

Sir could you please upload courses for free

Very helpful indeed. Thank you so much.

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

Great class Sir. Kindly do a video on solar power generation, net metering and gross meterin

Could you explain about transposition tower in AC transmission line?

Could you explain about transposition tower in transmission line?

Isn't HVAC is also Bi-directional. When a powerplant needs backfeed it uses the same transmission line to start the power plant.

Thank you for the video. Isec has unit of A, Isc also has unit of A. So Z must be dimensionless. It can't be impedance. It is a factor. Right?

Good job thanks

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

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.

Impressive knowledge such a beautiful and easy to understand all your fantastic educational valuable videos Thanks and best regards ☕☕
