We need to close the valves near bucholz relay before inflanting air cell baloon , otherwise transformer main tank PRV will operate with that pressure .
Sir when oil leakage happens in transformer, vacuum may creat in conservator.Also mog will show full oil level.how do we know there is an oil leakge or low oil level from mog
Sir thanks for this great video but sir aik swal confused kar Raha hain agar temperature barhta Hain Tou nitrogen gas Kaha jay gi aur agar wo Kisi value Kay through Nikalti bhi Hain Tou air Tou normal condition main bhi Nikalna chahiyah
as you see, the air is inside the air cell, which is at atmospyaric pressure, the air inside the air cell is released through breather, when the oil expaneded during the tempreture rise...
Nice sir. But one question arises is that can we top up the oil from either of the Air valve that are on the top of the conservator instead of thereal charging valve shown from the bottom.
no, air valve is to remove air and it is natural that the air trap on top, so if you want to remove air, it should be from top. so oil ahoud be fill from bottom only....
One issue arises in my Station. Oil is flowing thtough breather pipe approximately 200ltr oil already flow through breather pipe??? What is the reason???pls explain
without oil? fill the nitrogen or dry air at specific pressure, and keep the air vent of conservator open, if the pressure maintain then there is no leakage.
Sir I have a 12 MVA furnace transformer , after installation of TRF. main conservator showing full in MOG , but when we try to drain the oil from buttom drain valve again oil level increased above full condition....Sir can you tell me the reason behind this ? How can I confirm the actual oil level inTrf.?
which procedure you follow for chaging of air cell? it may happed that the bellow may not charged fully at the time of charging... i e not expanded fully...
In that case, there may be some minor leakage in the air drain valve shown in video, In winter, contraction of oil occurs, so the oil chamber of conservator tank create heavy vacuum and try to get air from out side and once air enter in the conservator tank the air cell discharge, You need to fill oil slightly more then prescribed in the conservator tank to overcome the problem... Thanks for watching 👍
If some oil leakage is there in main tank and oil level in main tank decreases, then from conservator tank oil should move from conservator tank to main tank but due to vaccum in conservator tank how oil will move towards main tank ?
if the air is not shown in the prisamatic glass indicator and the level of the oil is MOG is up and down as per the oil temprature then air cell is in working condition.
Problem happened that oil come out from PRV & MOG bolts. At that time, Oil level in MOG 3/4. So, thinked it may be due to oil more in conservator tank & pressure created inside. So, Oil drained & problem solved of oil come out from PRV and MOG bolts. But still thinking what exactly happened & how pressure created inside....
the oil level was High in the consevator tank.... when air cell is available in the conservator tank, you need to fil the oil at 30°C level or the filling level, which is mentioned on the MOG... as the oil level was high... there was no any space for expansion of oil, so it creates leakage from the poor joints... as faced by you...
kindly note that, the pressure of nirogen to be taken from 1 to 1.5 PSI....
We need to close the valves near bucholz relay before inflanting air cell baloon , otherwise transformer main tank PRV will operate with that pressure .
Thankyou for working guidance of conservator air cell type.
Go ahead . Now my concept is clear.nice explanation.
Nicely explained, clear all doubts
thank you... for your compliment...
kindly share to others and make them start learning with this channel...
Sir your videos are just awesome 👌
Thanks for detailed explanation
Thank you sir your video is very helpful
Beautifully explained sir...
very insightful, thanks so much
Sir when oil leakage happens in transformer, vacuum may creat in conservator.Also mog will show full oil level.how do we know there is an oil leakge or low oil level from mog
Nice explanation Sir
Very good 😊
Lens me full dikhayega to mog me bhi full dikhega ki ?
no.
Sir air cell conservator type tr ka filtration karna ho to aie release valve open karenge ki nahi.
yes you should, after filtration when oil comes near atmospheric temperature , you should re-charge the air-cell.
Sir balloon kon sa material ka hai jo oil heat hona pr koi impact nhi hota
Zada MVA ka transformer per air cell me 1.2-2 bar hi nitrogen fill he yah zada karna padega?
Sir thanks for this great video but sir aik swal confused kar Raha hain agar temperature barhta Hain Tou nitrogen gas Kaha jay gi aur agar wo Kisi value Kay through Nikalti bhi Hain Tou air Tou normal condition main bhi Nikalna chahiyah
nitrogen can come out from breather... as the oil in the consevator stretch the air cell due to vaccume in the conservator tank.
Well explained Thanks...
Sir, agar Aircell wala valve agar close rahe Jaye in transformer charge condition kya hoga ??
oil leakage may observe from anywhere in the transformer body.
@Insighttecs why
Sir ji oil gram hoker kaise failega apne tho pura conservator hi oil se ber diya pls reply
as you see, the air is inside the air cell, which is at atmospyaric pressure, the air inside the air cell is released through breather, when the oil expaneded during the tempreture rise...
Tell me whether aircell external pipe with breather connected with tank directly?.
Very very thanks sir
Nice video sir..if any issues create by Conservator tank level..that Can I realeasd air from conservator after installation.
Is it Ok or not sir
no, if you open the air went of conservator tank then the bellow will be release...
Air cell aegr fet gyo ho to kese check kre sir plz es pr video beney. Thanks sir
Sir,Can i charge air cell by blower
Yes
Sir 2 identical prismatic lens conservator tank q rehata hai,
Abtak maine sirf ek hi dekha hai

One issue arises in my Station. Oil is flowing thtough breather pipe approximately 200ltr oil already flow through breather pipe??? What is the reason???pls explain
is that conservator with air cell or without air cell?
Is video me oil ka expansion or contraction bhj add krke breather me air flow btaye to or asaan hota। When and how aircell draw air in it।
if we still have air surrounding the air cell, what will hapen during oil expand?
if no any leakage, nothing will happened for some ammount of air.......
Nice Explain
Nice explain
What the reason coming frequently buch relay
is there concentration of gas in the bucholz relay?
then you need to make DGA anylisis of the oil, there may internal fault in transformer.
Keep posting new videos
How to inspect aircell during inspection
without oil?
fill the nitrogen or dry air at specific pressure, and keep the air vent of conservator open, if the pressure maintain then there is no leakage.
What material has been used for aircell
Sir, what is the advantages of air cell vs normal conservator tank?
Air cell separates the air from transoil. Avoids moist air contaminating the oil.
सर आपने बहुत अच्छी जानकारी दी. पर मुझे एक प्रश्न है की अगर ट्रान्सफॉर्मर मे अगर कोई फॉल्ट आता है तो उसमे जो गॅसेस तयार होते है वो कैसे बाहर निकलते है.
it traped in bucholz relay...
Thanks 👍

it may happed that the bellow may not charged fully at the time of charging... i e not expanded fully...
Breather se oil bahar aa raha hai esa knyo ho raha hai
may be your air cell is damage if conservator of your transformer is with air cell..
eles, the oil is over flow due to temperature
How to change silica gel in air cell conservator
same, as for without air cell....
once air cell charged, the working of silica gel breather is at atmospheric pressure...
@@Insighttecs Thanks for replay, have you any video on diaphragm sealed type ,,,
In winter season,Aircel was found in discharge condition, what is the reason???
In that case, there may be some minor leakage in the air drain valve shown in video,
In winter, contraction of oil occurs, so the oil chamber of conservator tank create heavy vacuum and try to get air from out side and once air enter in the conservator tank the air cell discharge,
You need to fill oil slightly more then prescribed in the conservator tank to overcome the problem...
Thanks for watching 👍
How breathing action take place
If oil expands then how it manage
when exposed to air by breather what will inside air cell after one year nitrogen or air?
nitrogen with air, it will depend on the expansion of oil of transormer and contraction of air cell
If some oil leakage is there in main tank and oil level in main tank decreases, then from conservator tank oil should move from conservator tank to main tank but due to vaccum in conservator tank how oil will move towards main tank ?
pressure of oil is higher then vaccum... due to large quantity...
Sometimes oil comes from breathers ,what will be the reason
How to check air cell is in working properly or not?
if the air is not shown in the prisamatic glass indicator and the level of the oil is MOG is up and down as per the oil temprature then air cell is in working condition.
What effect in pressure air cell 1.2 bar and weather pressure 1 bar in case oil expand air is remove in air cell but oil down that what happened ?
That time pressure of refilling air ?

Sir how to top oil in online
you should not..., but if required you can add from bottom valve of conservator tank with all safety precautions, as narreted in this video

👍🤝🤝
Can I ask you some questions
In which principle Aircel works??
Why nitrogen is foiled in aircell and not air?
nitrogen is dry in nature and it may dry more...
you can fill air also but it should be dry...
first priority should be nitrogen..
Aircel Discharge
Thanku aie
अगर गलती से air cell मे oil भर जाए तो क्या करें
Air cell se oil ko nikalna padega kyu ki us oil ka koi use ho ga hi nahi
Oltc ke breather se oil leakage ho raha hai
Drain out oil from conservator tank.
