Great leacture in the world

[@ee66abhishekverma18]

I have subscribed... I like how you teach with real life eg.

[@MohamedAli-fn8kh]

Excellent

[@chinnakarlapraveen9966]

Thank you so much sir

[@chaduvulahemanth3974]

happy to know this information. Thank you sir

[@suryanath8464]

Videos from this channel are superb !!

[@sureshbabu-tj8fl]

Excellent...Thank you for the service 👍👍

[@tel46ninadyadav79]

Thanks for this unique info sir

[@jeenusrinu8796]

Hii sir.i want to measure 15 amps.but meter shows 14 amps while doing practical.meter maximum reading is 20 amps.then you can explains error calculation for different error symbols you explained.

[@devendrasingh8403]

Thank you sir good keep it up Sir i m sharing this video to my friend also Good day

[@rishigautam9295]

Awesome..

[@zaidi0to1]

Thanks for listening to my advise .

[@anilpperisetla]

Sir please make a video on , why semiconductor material is used in underground cables 11kv above,and their advantages.

[@periyasamy774]

Thank you Sir...

[@prakhyathmunna254]

Nice one !

[@electricallearner]

Sir why we are connected #live wire right side on switch board #socket?

[@satyabrata180]

Very nice sir

[@prudhvirajrouthu3927]

Sir... plz explain how work solar fence energiser.

[@alammd.samsul8424]

ive a used- heavy machine stiker worn out ,how i place her ,where can i get a help,vaiaaaa.......with love amd.

[@sujoybhattacharjee4500]

Sir I have a little doubt.If the instrument has full scale value of 30 volt, then how can it be tested at 500V or 2kV?

[@akashkarmakar1572]

I think to test those instruments sustainability with a very short period of time like 500ms or 1s.

[@akashthore99]

Large voltages can be stepped down upto a particular range which your instrument can record and then you should multiply that reading by the factor which the voltage was stepped down. In short, that's what PT( power transformer) is used for and similarly CT( current transformer) for measuring high currents. Hope that helped!

[@30mAkills]

I will tell the procedure: All current carrying terminals are shorted or jumpered together. The reqd high voltage is injected between the terminals and non current carrying metallic frame or body. The device should withstand this test for 1 minute without any damage/failure. Note that higher the withstand voltage higher the cost. This test is known as HV withstand test. The voltage is selected based on historical data, otherwise it will be destructive. Meggering test is another common test done for testing the integrity of Insulation resistance. The injection voltage is usually 2x of normal working voltage of the device. Hope this info helps.

[@jeenusrinu8796]

Sir above mi ammeter you shown scale is non linear .if current shows between 0 to 5 amps then how to read the current manually in this condition.this is my doubt.please explain

[@bandarikishore021]

Make a video on energy meter and how to calculate electricity bill sir

[@northkoreasupremeleaderoff721]

Maths demo lectures link wr?

[@r.saisundarsharma5553]

Anna if we send 11kv we get 10kv as 10 percent drop, so do the 11kv motor required 10kv🤔🤔

[@gnanavel16]

Really appreciated. Thank you.

[@Pradeepdurgam]

How to identify a motor rating without nameplate details please explain???

[@sridhargedela736]

sir if one(1) is inside star symbol then 1kv was tested?

[@divyasrijayini249]

Because of gravitational force we have to keep flat..our sir said

[@AbhilashKsupernovaabhi]

Awesome Loved it. I was searching about it in Google & was unable to find it.

[@r.saisundarsharma5553]

They said gravity will effect reading AND later by E.Intruments I thought reading may change incase of GRAVITY ONTROL

[@AbhilashKsupernovaabhi]

Hello Sir, In ammeter there indication "B" after stars what does it mean
