Knowledgeble video.. thank you sir, here i request please make video and give explanation on faulty DB test by megger, that if my phase and earth short then how to find the individual faulty circuit
Can you please clarify is it going to be totally fine if we don't remove electrical appliances while testing IR I'm bit confused that applied voltage is DC or Ac.
Explanation and video is easy to understand. Thank you so much brother. Is megger test done for lighting wires also or only for power cables ? Is megger done before panel termination or after. As I can see it is done after termination but please clarify. Thanks
Megger is done for wire and cable both, first we do meggering for wires and cables before connection after that we do meggering( insulation test) for DBs
The main breaker is switched off only which is connected to Smdb. All outgoing breaker to each circuit is switched ON because we are meggering here the final db and all the final circuit in it.
Sir you said that in DB test we wont check Between Earth and Neutral ..but in video you checked the megger value between Neutral and Earth also ? Can you please guide
Sie ek video polytechnic student ke liye banayea electrical diploma student ke liye ,taki hum sa student ko kuchh positive rasta mile ,very confused about future sir
The first and foremost fact you didn't mention in this video is that do we need to do this test in onload or offload conditions means main CB on or off. Bcz you said " niche karke karna hoga" .. pls mention it clearly to non native speakers also can understand.
Yes forman can become engineer, later in his career if his performance is good he can do distance course in engineering and obtain degree without quitting from job, then he can apply for promotion
Hi sir, you did the test while the breakers were switched off. I am confused whether the terminals of the breaker were of incoming voltage or outgoing. Please clarify.
Hi sir, I got 5 years of experience in dubai as an Electrical Engineer. Now i lost my job and searching for new opportunity, Its been 3 month i am hunting. Can you please help me out to find a job.
Sorry to say you totally wrong in saying that -- Your all appliances should be on. -- This suggestion and procedure would lead anybody to failure in finding out the Insulation Resistance of your wiring and would lose any possibility to find out any fault in the system. Rather all the Switches must be in 'Off' position. Rather it would be much much better if you dis-engage all the appliances and devices from their sockets, holders etc. And only in that case you would be able to find out the true Insulation Resistance of all the cables with respect to one another. Sorry for challengeing you. Kindly record your Vlog again or please remove it. Thank you.
You are right in some aspect, but here I showed you regarding the insulation resistance with earthing wire, What you are telling is correct if we check the resistance between phase to phase or phase to neutral, in that case if the appliances is connected and switched on you will unable to find the proper result. But with earth wire there is no problem like that because the main current flows in phase and neutral only. Even if you work in UAE and at the time of inspection if you closed the switch and authority come to know that you closed the switch then they will tell you to open switch before meggering the final DB. For cable meggering your point of view is correct.
@@EngineerTaj Thank you for kind and quick response, it's right that I may not be aware of all the possible uses and techniques of Meggering, yet I would insist to say this procedure does carry some serious risk of exposing your appliances to high DC voltage 500 V/1000 V, if one accidentally applies the testing probes to the Phase/Live and the Neutral of the circuit under test in case the appliances are powered by AC? And one would get the lowest possible ( useless?) meggering result. I didn't use a Megger ever. I got UniT UT 526 Insulation Resistance Tester & RCD Tester, didn't power it on. I'm waiting for the electrician to lay down a new wiring ( as the previous wiring has been faulty ) in our home with two separate Isolated Earthings. I have serious plan of installing a 3KW Hybrid Inverter ( equivalent to the Indian Cellcronic brand the New 6G ) with 4KW PV, with protection from lightning with LA. I intend to check the fitness of the wiring and also the fitness of the Earthing wires and also the Earthing (under ground) Electrode. Hence I trying to chew as much about Meggering as I can before I indulge in testing. I took pain to devise an electrical circuit around a single rotary 4 Pole 2 Way Switch in a way the same Earth-Leskage and Lightning-Arresting & Over-Curent-Protection circuitry be used on the Inverter as well as on the Utility line. Your kind support would be appreciated. Thank you.
Sir
Aapke samghane ka tarika bahut lajwab hai ,yah video dekhane se pura achha se samgh me aa gaya,
Bhot zberdast g bhot izafa ho gya ilam me g Mera job status electrical technician Hy bhot Kuch seekhny ko milta Hy apki viedio sy
Thanks
I've watched all of your videos .😁 now I can do everything related to LV, from calculation to termination.
Appreciated Man.
Defined very clearly.
Sir aap ka treka bahut achha hai samjhaneka
Informative Sir
u explain very good man 👍🏻👍🏻👍🏻

V v informative knowledgeable nice explained ....
Very good sir thank you
Bohat khub Sir g
Abhi tk AP kaha thy
Good job 🌹
Electrical equipments laga rahega ya hata ke check karenege ,ye DC damage to nahi kar degi electronic equipment ko ?
Dear sir kindly update a video regarding Electrucal foreman work responsibilities..

learned alot
Sir ... electrical power engineering k liye konsi software sekhna chahiye...?.
Autocad, revit if you are in need
Taj bhai diploma engineer ko kya electrical design draftsman ki job mil sakti h aur salery min kitni starting ho agar job milti h to
Brother Great video as always..
This test is before or after light fixture,socket, isolator installation ?
Yes before
Nice
kindly upload more tests used in construction site
Good
Thanks
Sir you said all switches should be on but you have off the breakers..?
The main breaker is switched off only which is connected to Smdb. All outgoing breaker to each circuit is switched ON because we are meggering here the final db and all the final circuit in it.
@@EngineerTaj Thanks for replied..
@@EngineerTaj please can you do meggering for indoor Transformer.?
Main breaker ku off mode me check karna hai
Sir you said that in DB test we wont check Between Earth and Neutral ..but in video you checked the megger value between Neutral and Earth also ? Can you please guide
In DB insulation test we dont check between neutral and phase,
@@EngineerTaj ok thnks sir
Jai Hind 🌹
Good video.
What is Db?
DB - distribution board
thnx
Welcome
Hi bro please do a video about electrical drawing and project report in details

Dear sir,
Please mention the resistance values to maintain and allowable values as per standards.
Thanks & regards
Tnx sir

can you please do english subtitles
❤
Isme maximum value kitna m ohm he
2mega ohm
Can electrical foremen chance to become electrical engineering
Degree should be taken
Yes forman can become engineer, later in his career if his performance is good he can do distance course in engineering and obtain degree without quitting from job, then he can apply for promotion
Bro I have exam next week for sewa as an assistant electrical engineer ,I don't have any idea about thia exam can you please guide me
Part 2 please
I made 2 videos on megger, do you want one more?
5 megha ohms hai
Achha hai ki nhi
For final circuits it is ok
Hi sir, you did the test while the breakers were switched off. I am confused whether the terminals of the breaker were of incoming voltage or outgoing. Please clarify.
4 + 4 × 4 = 4 + 16
= 20
Jo circuit problem Hy usko rectify Karke bata bhai
Please put subtitles please
Some of them are ready
