Excellent informations.

[@ssreee]

Nice explanation. Pls put more videos on a regular basis.

[@rahmanrafeek534]

Bro unga videos kku romba naala waiting

[@iqbal_kvd]

I see your many videos everything is useful

[@gopinathandayalan9377]

Superb bro thanks & regards

[@thulasiram5156]

Very well explanation. Keep continue

[@vijayagamudayar]

Wiring epdi kudukanum enga kudukanum sona usefull ah irkum bro

[@vignesh2670]

Very very useful information thanks for sharing.bro

[@sugumaransivaraman2116]

Hey samiye ayya samiuye
Super information

[@bhavangs]

Excellent please make videos for SEF and differential protection

[@reyasmohammed2250]

Bro, very good explanation

[@sumangorai2031]

Nice explation sir , can u make this vedio in English or Hindi. 🙏🙏

[@arun4846]

Superb 👍

[@ganeshsundar5489]

Hi…. I ts fantastic…. I am sure that it will be very useful for engineers in EPC..Good video brother..

[@prakashksp2918]

Nenga vera level

[@sureshramanandhan8502]

Bro nice explanation. ..pls make Electrical equipment testing & Commissioning Videos.

[@brightstar6587]

Sir, ur video are really good, plz make some vdo in ENGLISH language

[@jasssimm8422]

Please provide one video for differential protection for transformer and busbar sir , it will be very useful .

[@velusamypothiraj2300]

Super , please explain how to testing this scheme. We expecting same on micom motor protection relay and solkar relay reyroll make for feeder protection.

[@santhoshr53]

Plz make corrections of neutral ct polarity

[@Singh-hd3cv]

Please make same video in english or hindi language

[@Sarojsandarbh]

Very nice video sir…if possible please make videos in English/Hindi also..

[@owinookello9358]

good videos sir but use English please

[@chituarasan9892]

Hi bro,
How do you fix the CT Polarity..
P1 & P2

[@prakashksp2918]

Sir nenga father of electrical

[@shrikantushkela8331]

Sir, can you explain in English or english subtitle

[@muppudathiseenivasan7006]

Bro machanical type relay internal operation pathi sollunga bro

[@seablue1085]

Plz add english sub, thanks

[@govindrajan3435]

Sir ct ratio calculate ku I2/I1 thana apdina 5/3200 ana neenga pottu irukinga 3200/5

[@anilshemade6048]

Plz give the english sub titles.

[@siddayoga]

Bro how to make animation video like this

[@generalengineering1194]

Microsoft PPT

[@lokanathpanigrahi3208]

Sir please upload video in hindi or english

[@venkatsan8825]

Hai bro what's use of register in this circuit's

[@generalengineering1194]

10:07 to avoid External fault

[@venkatsan8825]

@@generalengineering1194 ok bro this register avoid to external fault.
why register not limit to neutral fault current in the circuit

[@generalengineering1194]

Stabilizing resistor is limit the fault voltage,that means
Already we calculated the fault voltage level, if fault voltage is more than the limit it will covert to heat like our fan regulator

[@venkatsan8825]

Ok bro thank you

[@RamKishor027]

If possible try to make videos in English and share

[@vijayagamudayar]

2666.75*20per 533.35 epdi 32000

[@generalengineering1194]

2666.75 *20% = 533
2666.75 + 533 =3199 that means 120%
