- AC power supply system without earthing, ungrounded, isolated or insulated neutral and its advantage & application is explained in this video. The difference between grounded and ungrounded systems is explained. The difference between insulated and earthed neutral systems is explained. The effect of 1st earth fault and multiple earth faults or 2nd fault is explained.
The Insulated neutral can be got by using one isolation transformer. Insulated AC supply is used in ships, train engines, the chemical industry, and telecommunication. The use of isolating transformer in an insulated neutral system (floating neutral) is explained.
An educational tutorial on the power supply system, electrical and electronics engineering 344 by G K Agrawal. The lecture is given by a person with circuit design and industrial experience.

Sir your videos are really very helpful.i can't really express my gratitude for your lessons.many people gathering huge experience however their knowledge doesn't remain good.You have cleared my many confusions and queries.
My humble request to you is that kindly make video on Differential ,earth fault,restricted earth fault,Distance Protection as soon as possible.pls sir
Watch experience-based electrical and electronics video on this channel
Very nice explain
Sir i am watching all of your videos, and love the way you are teaching. Thank you sir.
I am From Bangladesh
Thanks you BABUJI, FOR YOUR VIDEOS,
I am a 2to 3year old your TH-cam video viewer.
Super👌👌👌👌
Comments welcome
Very helpful
Very nice..practical video. In our ship practically we experienced..one phase was shorted with earth nothing was happened..But while synchronizing with shore it was started burn...
Sir, This video is awasome
Well explained
Thank you man.. really very nice explanation
Amazing.
thank you very much!!!💖🙂
Thank You Sir...
Nice video sir
sir ,this is the best explanation i saw ,u r amazing
You can watch my other 370 videos. Try just 1 or 2 more.
Excellent impeccable KUDOS
I am continuously watching your videos... it's very useful my career... for kind request I want power electronics videos please make in all videos english... because most of your videos showing hindi..
Thank you sir...
Many videos are made in English version also, if not then CC is written in English in many cases. There is a playlist also for all English version videos . In many English version videos, CC also is written in English.
@@GKAgrawal2 ok sir... please put in power electronics videos
Sir winding sikne ke liya kucha tips hai aap ke pas.
Please make it more videos for power electronics
Sir how we earth the welding machine on ships
Good Morning Sir. Kindly make a video on how the current density of bare copper conduit is arrived.
There is no standard method. Current density allowed depends upon project, application, temperature range, past experience etc.
If somebody new engineer calculate in a new company, then very soon they will realise that smoke is coming out at the project side, and current density will be reduced based on this. However again they will know that smoke is still coming out but during summer jun month only. Then again current density is reduced.
But they will realise now that cu cable had become too thick, and there is no place in the equipment, so entire equipment design need to be changed.
I think you understand now. That experience play lot of role in real world.
However in college exam, only calculations and no experience.
Sir g kya home arting me mcb lga skte h plz rip
No
Sir,
If we do not earth ,nutral in substation ,and we touch a live wire,we get shock?
Watch my video on Electric shock during walking on the earth. You will get answer of your question.
Sir I want to ask you that when no load on transformer then why pf is low.
Transformer acts like a inductive load also.
@@GKAgrawal2 sir if we synched solar power with electric power will it effect on power factor ?
@@GKAgrawal2 please sir make a video on both topics
Excellent sir, I have one question u have explained in neutral grounded system if phase touches ground u said MCB trip
But I think the current will start to flow to the ground that is a leakage current
Am I correct sir
Please correct me if I am wrong
Yes, it is like leakage current. But this current flows in MCB also.
This is actually short circuit current.
We call it leakage current if it flows due to some high resistance path between line and earth, like dust, moisture, insulation failure etc.
There is no legal language of currents. All currents are called with different names for understanding purpose only.
If it is not your exam, then call it by your name like mailtoippan current. I myself has called one reactive power as agrawal power in our one project to exaplain others. You call it as you wish, but equipment should work.
Legality comes when there is agreement between 2 parties. If it is for your design use then no problem.
For example your friends and parents may call you by different names. No problem. But you cannot give different names to bank or office etc.
Sir, please make a video on arcing ground.
watch my video on AFDD to know exclusive information on arc.
@@GKAgrawal2 Thank you sir 😊
Sir ji bike ki battery pe kitni led jla sakte hain or कैसे. Video please
Also, what are the safety hazards of not having an earthing pin , suppose in maximum appliance, there is two pin plug only..
May I ask more examples of Insulated neutral and earthed neutral systems, sir?
Ships, sometimes on vehicles, Oscilloscope also
What are the safety hazards of insulated neutral power system?
In insulated neutral system, how 2nd earth fault will be detected ? As the path is same as first earth fault.
Difficult to understand. What type is preferred for house wiring?
For the house, we get an earthed (at substation) neutral system. No choice from our side.
HI SIR, IF WE TOUCH IN PHASE LINE WE DIDNT GET SHOCK RIGTH?
You may still get electrical shock.
@@GKAgrawal2 in insulated neutral system if we touch phase line , how circuit will complete since the neutral is not connected to earth, how we get shock?
Capacitive coupling between long wires and earth, transformer windings and a transformer body, varistors between earth and wires, two people touching wire at the same time etc.
Rotor Earth Fault
सर जी हिन्दी मे बताया करे ....धन्यवाद।
यह वीडियो हिंदी में भी है
Nice, but hardly understandable this "English". Maybe subtitles would be helpful :)
I will try to add subtitle in English. However my many videos have subtitle in English
Your English accent is very difficult to understand 🤣
Watch Hindi version of all videos.
Well explained
