sir aap ka channel abhi subscribe kiya video dekha bohot acha h aur bohot ache se samjaya h aisa itna koi nahi batata thnxx sir aap k video dekh k bohot knowledge milega practical ka sir bas thod thoery b add karo sir nd starting se dikhao kaise connection kiya h kya kiya h
Sir isme gap 2.5mm ka lia hai.. To 39.9kv/2.5mm aayega na breakdown voltage.... Mtlb breakdown voltage per mm kam aayega.. 16kv/mm aana chahiye na sir? Please clear it🙏🙏
Nitesh Bro...U r doing Great Job. I need your video lecture regarding electrical drawing study, which I watched earlier but these are not showing/available on ur channel. Please provide the link asap. Regards & Thanks
Nice explanation, pls can you make more video on it. 1) how to collect oil from the transformer, which equipments need to be use. 2) you didn't show the limit of the oil, means how much oil need to put in the glass container ? We didn't see it clearly either the electrodes were completely emerged. 3) if the oil dielectric strength is not good, after that which tests or method need to be use again to check the oil. 4 ) clarify the minimum and maximum value of the BDV, need list according to the transformers values. 5) which kind of transformer is inside the testing machine ? Step up or step down ? Single phase or three phase?
1)From T/F oil collecting valve 2)Electrodes should be full dipped 3)Vacume the T/F oil & Dehydration of T/F 4)Above 50kV for 132kV 5)Single phase 220V to 100kV
ct current transformer kya hai or pt potentional transformer kta hai or ab switch kya , jamper kya hai .isolater kya hai , busbar kya hai do chainal kya hai duo fuse kiya hai ,
it depends upon the ratings of transformer and voltage level. however for 400kV Above considered value is above 60kV but all engineers would consider good value so that no risk can be taken. since Practical sense is more importantly considered rather than theory value !
Please explain..... 1 complete test report of T/f .... Main & oltc..... (explains all parameters....... Like dielectric strength ;tan delta at 90°c...... DGA test...... Pour point)
Transformer oil ka DGA test me agar parameter sahi nahi aata hai to uska filtration karna padta hai. Esliye sabhi equipment jis me transformer insulating oil hai uska DGA test hota hai har sal.
Unit is kV which shows that dielectric strength of Oil is broken at xxxxx kV. However, if you increase the gap between the electrodes then the kV will increase.
Sir क्या आप बता सकते हैं कि distribution transformer के high voltage test के लिए कौन सी size (mm) का केबल इस्तेमाल करना चाहिए, जिससे curent suply दी जा सके tranasformer को
High voltage test me sirf voltage high hota hi. Current milli Ampere me hota hai. To aap kisi bhi size ke cable ko use kar sakte hi. Par aapko uske liye bahut jayda safety follow karna padega.
Nitesh Boss... You explained in a clear way.. But for BDV what would be the Time..?.. I mean 35KV @ 2.5mm Rod gap for how much time it shall be withstand?
Helpful a lot for an Engineers ,who r practically unaware about such Test......
Thanks a lot Gentlemen..
Thanks.😊👍

Ha aap.shi nikhalna hai,lekin ak transformer oil ka vbd almost 30kv/mm hona chahiye mtlb ye esse test krne pr almost 75kv pr break kre
Excellent explanation. Very informative
Very good practical knowledge

Sir 100kv transformer 42 brake down voltage is it required to filter oil and heating treatment for transformer
Is the bdv of 220/66 kV transformer will be same 60-70 kV if yes then how it will resist 220 kV tension please explain

Is it for new trfmr or old ,coz for new trfmr breakdown voltage should b 80 kv ,plz reply ??
it depends upon the ratings of transformer and voltage level. however for 400kV Above considered value is above 60kV but all engineers would consider good value so that no risk can be taken. since Practical sense is more importantly considered rather than theory value !
@@NiteshKumarElectrical 400kv or 400kva??
Electrod me gap 2.5 hi kyu rkhte he
Super 👍👌
awesome sir.
sir can u tell us the question arises for site supervisor electrical in interview and there answer also.
I will be covering all complicated topic. Others tou can prepare by your syllabus only. Focus on basics !
Nice👍👌

Sir why 2.5mm gap is maintained in between 2 electrode , why not less or more ??
naga ranjith We do 2mm and 1mm gap here in USA
सर ट्रांसफार्मर के मेंटेनेंस और प्रोटेक्शन पर भी वीडियो बनाइये
hy sir you video is really useful plz can you tell me what is price of testing machine which shown in video?
Nice video.
Sir 7 MVA ka kya value hoga bdv test ka
Greater than 50 to 60kV at Ambient temperature would be excepted.
@@NiteshKumarElectrical thanks sir
Sir please make vedio on transformer oil filteranation machine detail like construction,working, it's filter.
Thanks you for information
2.5mm ka hi gap kyo hota hai, usase jyada ya kam kyo nahi
BDV Test Kit es setting par correct value dete hai. Jyada ya kam krne ke liye kit ki setting me change krna padega.
Nice sir breakar mentence Ka video banaiye sir
Bilkul banaunga.
Sir transformer protection and maintenance par bhi video bnaiye plz ...
Nice video but instrument using is not latest we use megger OTS80AF kit
950 kva ke transfermer me oil dielectric strength kitna hona chahiye Or ye kaise calculate karege transfermer ke kva ke rating ke according
30 kV/mm
BDV value voltage rating ke according hota hai. th-cam.com/video/HuKlMXpzR1o/w-d-xo.html

Sir mujhe transformer ke sare test dekhne h Kon Kon se hote h
Anuj Kumar ! जल्द हीं टेस्टिंग वे वीडियो अपलोड करूँगा।
Transformer k different part sy oil sample liya jata hi maximum 55 kv tak acha result hi.
nice video sir
Amazing video 👍
Is that unit is kv/mm? Or the kv/2.5mm
Unit is kV which shows that dielectric strength of Oil is broken at xxxxx kV.
However, if you increase the gap between the electrodes then the kV will increase.
kV/mm
Boss Kaise ho.
For 33kv BDV is 35 to 40 kg but for 220 kg line why around 50 kg BDV.
Gap kya 2.5 mm hi hona chahiye
हा जी
Thanks Sir,
Please make a video on a DGA test

Nitesh Boss... You explained in a clear way.. But for BDV what would be the Time..?.. I mean 35KV @ 2.5mm Rod gap for how much time it shall be withstand?
There is no time line. If dielectric strength of oil is weak then this will break down at lower voltage also.
