Thank you! I worked in avionics for 50 years and never knew how the 50 hz came about. Very interesting!

[@ThePiSquareAcademy]

00:44 Electricity in India uses 50 Hz, while in the US it's 60 Hz 03:48 First accidental invention of AC generator and early applications of electrical power 06:54 Thomas Edison's invention of practical incandescent lamp and its impact on power transmission 10:26 Transmission of power at low voltages results in high current and losses. 13:45 First AC transmission in Italy used 130 Hz frequency. 16:52 George Westinghouse saw opportunity in AC and modified transformers for efficient transmission 20:07 The War of Currents led to the adoption of different frequencies for electricity transmission 23:22 USA uses 60Hz, Europe uses 50Hz 25:58 Electricity frequency selection is based on historical events and technological advancements. 29:06 Higher voltages lead to low transmission voltage losses Crafted by PiSquare AI.

Thank you sir for understand whole

[@parassharma263]

Sir why transformer size reduce when we increase frequency of transformer

[@rajkamalkakoti1584]

For same voltage rating, with increase in frequency no of turns per phase of a transformer decrease, which decrease the overall size of the transformer. This high frequency and smaller size transformer is used in aircrafts.

[@prasadsowale1931]

Just go through the output equation of a transformer .. in which you will get Q = 2.22 *f* dimensions of transformer .. So when you increase the frequency , for same output transformer dimensions becomes lower ..hence its size reduces.

[@powerelectronicsguy2622]

With use of high frequency, time duration of magnetisation of core in any direction decreases. So for same current, we need to handle comparatively lower flux. So we can use a transformer with smaller core. Transformer is noting but a two winding inductor. Say when we give DC voltage(one directional) to inductor, current will keep on rising. So it the flux with time. 50hz = 0.02sec. or one half cycle is 0.01sec. now if we increase the frequency, flux will not rise as in case of 50HZ. So small flux can be handled by a transformer with lower core area. Thus size reduces

[@EphemeralProductions]

windings. You need more windings and bigger cores the more voltage is involved.

@24:18 both british & US have second as a unit for time. How can you say that it is not fitting in their metric system? Dont just assume? Do they have 50 seconds in one minute? That is not a proper reason. If it is kindly further explain the metric system. Thanks

Thank u sir. Most mysterious question. And please explain why we can't store the ac energy ?? In quara so mny explanations are there..no one satisfies me..plz consider it sir

[@vugyhy]

kasyap sharma yes I am curious to get the answer

[@ThePiSquareAcademy]

Sure we will do it soon

[@vugyhy]

When ac supply was invented till that time there was no ac generator so how they generated it and how they set the frequency.

[@kasyapsharma424]

@@vugyhy ...the interesting fact is ..the o/p of the dc generator is also a.c ..just we r converting ac to dc by using commutator...sir also told that , unintentionally they get ac through dc generator ...i hope , this is relevent to ur question

[@rowdyrokers6308]

Hats off👏👏👏

[@vigneshsrini1497]

Please differentiate between commutators and full bridge rectifiers??

[@prasadsowale1931]

Rectifier is the device which converts AC into DC but commutator is a set of coil which changes the direction of current during operation . Commutator acts as a rectifier when machine is used as a generator and it acts as an inverter when machine is used as a motor .

[@vigneshsrini1497]

@@prasadsowale1931 thanks, do u have any circuit drawing reference for commutators.

[@prasadsowale1931]

The drawing of commutator is available in B.L. Theraja .. in that will get commutatotrs used for generators .. but we can draw the wave form just by changing the direction of current for motor also

Hello sir , your explanation is very cprecise , thank you for sharing these informations , please keep posting videos solar to this inventions ,

[@user-dc6ho3xp7w]

sir ..i have a question about load calculation and how to devide in 3 phase, there is a 125 kva generator loads are 400watt flood lights, how many flood light i can apply? how to devide on each phase ? are these inductive ,capacitive or resistive load? plz explain mathematically, and plz consider power factor if loads are inductive also generator's efficiency 80%. plz make a video on this topic thank you sir.

[@Inflec]

+uttam patel - With the information you provided I got a total of 312 of your 400 watt bulbs as the number which most fully loads your 125 kVA generator and can be evenly divided between the three phases (104 bulbs connected to each phase). The efficiency of the generator does not enter into these calculations. That becomes a factor if you must also know the size of the prime mover which drives the generator: 125kVA/0.8eff. = 156.25kW, or approximately 210hp (156.25kW/0.746 conversion factor). Assuming these are incandescent lightbulbs, they would pretty much be resistive loads (unity power factor). Hope this helps you. [Edit]: I got the bulb numbers as follows: 125kVA capacity/400 Watts per bulb = 312.5 (total), divided in turn among 3 phases = 104.167 bulbs per phase. Rounding that number down gives us 104 bulbs per phase, multiplied by 3 gives us 312 bulbs total.
