Hello sir I am just curious on an explanation video that you have made that is the moving train beeing mesurered ,do you know who invented it Because I have found some papers of my grandfather's and they are the blueprint of them so I'm trying to see if someone is claiming his invention from 1960's
1st, this formmula F=mf was invented long back and not 60 years back. 2nd any invention patent period is only 20 years. After that any body can use it. In automatic washing machin also, mass of the cloth is measured just after starting the machine. So formuls is known but implementation is quite difficult. Different engine manufacturers follow different techniques To measure and control. I studied 1000s of books, paper , articles, documents, discussion with experts, my own analyses, my own project in last 40 years. So I can not tell that which knowledge I got from where.
@@GKAgrawal2 Sir Ji Supply transformer me lgi earthing. Se Kya unbalance load ground ho jata h For example 30 amp unbalance h to Kya vo ground mein waste ho jata h Sir R phase 20 Y phase. 30 B phase 70. amps h to kitna amps unbalance hoga aur Kya ye unbalance ground me chla jaega earthing wire se aur waste ho jayega Plz....plz. Btaye sir
I contacted the manufacturer of the AFDD shown in this video. Their expert replied that, this AFDD can replace the present MCB at the incomer. I feel that if you want, you can retain existing MCB also. AFDD can be connected before the MCB.
Hello, what is the RSSI signal and how to extract it from the sinusoidal signal of the network. Can I use the fast furier transform, or use the two channels of the oscilloscope through the mathematical function of subtracting the sine current from the receiver current? I understand that this is a signal extracted from the waveform of the current consumed by the receiver?!
Good question. 4 to 20 mA signal transmission key liyey use hota hai. Adhik tar sensor key liyey. Yeh DC current hoti hai. Voltage ki jagah current use karney sey noise problem less hoo jathi hai.

I have a long-pending query. 1. For a balanced 3 Phase, positive phase sequence components current in Fig. (or diagram) show the direction of rotation in ANTI-CLOCKWISE direction and mention RYB. But, in moving ANTI-CLOCKWISE direction, sequence to face first IR1 further IB1 and at last IY1 2. Similarly for balanced negative sequence components current in Fig. (or diagram) show the direction of arrow ANTI-CLOCKWISE direction and mention RBY. But, in moving ANTI-CLOCKWISE, sequence to face IR2 further IY2 and at last IB2 It is not understandable. Till now, in every power system book, this is mentioned. For your ready reference, Page 424 from Power System VK Mehta.
You are asking as if you are complaining to some government or some supplier of some item purchased by you. Note that this is free teaching class. Any way, for negative sequence, direction will be clock wise, and not anti clock wise. Further I am unable to understand that what is not clear to you.

Sir
R phase 20
Y phase. 30
B phase 70. amps h to kitna amps unbalance hoga aur Kya ye unbalance ground me chla jaega earthing wire se aur waste ho jayega
Plz....plz. Btaye sir

*Sir You are doing very great work on youtube* 🙏🙏🙏🙏
Namaskar sir. Very nice explanation. Love from Bangladesh.
Very good explanation sir ji.
Very nice sir..keep it up
Very nice Sir 👍
Can you share one video switch gears maintenance and commissioning
Very nice sir
Thanks a lot sir for making such a great video!!🙏
Great explanation! Where to put or location of the AFDD in panel board? is it before or after the main mcb breaker?
AFDD has build in MCB. Any way it will work, you put before or after MCB. But I will contact manufacturer and ask them, where to put.

Sir some video about on grid solar inverter technology
Thanks sir pls make vedio on Relay
Video on relay working is already there.
@@GKAgrawal2 thanks sir but we wan to know about Numerical relay , Generator protection
Request you pls make vedio on numerical Relay wiring connection ....
Ok sir.
But do you know how does the overvoltage protection of the AFDD work ? I could not find anything about that.
You may not get. Due to commercial reason, concept will not be told by companies.
I want to buy afci where I can get it.
It is available online Amazon
Sir koy instrument me 230V Ac ke jagah 4 to 20mAmp kyou use karte he ... 4 to 20 m Amp 230VAc use karne pae kya hoga ....sir

Sir Ji
Supply transformer me lgi earthing. Se Kya unbalance load ground ho jata h
For example 30 amp unbalance h to Kya vo ground mein jakar waste ho jata h
No
@@GKAgrawal2 to Kya hota h sir unbalance load Ampere ka kha jata h
Sir is vajah se neutral pe bhi voltage aate h na kuch na kuch
Sir if inverter is installed with 1 phase wire and common neutral in house will RCCB work in main distribution box ????
If there is earth leakage current sese by RCCB, it should trip.
Sir vcb and ACB breaker ka GA circuit diagram ka vedio please . Pura details me. Sir please

Sir 100 watt bulb ka practically 38 ohm's
But theoretical 484 ohm aisa kyu
P=V^2/R. P= V^2/R
= 220^2/38. = 220^2/484
=1273 watt = 100 watt
Aisa kyu
