You all probably dont care but does anybody know of a method to get back into an instagram account? I somehow lost the account password. I would love any tips you can offer me!
I am a lowly 'low volt' (120/240v 1ph; and 3ph) residential and commercial (some industrial) electrician in South Florida. This is the first time I have really read/seen/heard ANY detailed information on transformers and their design and operational characteristics. Very, very interesting, entertaining and informative. Thank you. There is a guy named Mousa Al Manasif [2 years ago, from now 01/02/2022[], who complemented and thank for this presentation - but brought up a few things where he says there were a few incorrect statements made in this video concerning: "However I noticed two things that are incorrect: 1- OLTC on load tap changes are divided to two parts a. Diverter switch ( the arcing and the interpretation of the current, have separate compartment) b. selector switch ( the part inside the TR main tank which shares the same oil of the TR) OLTC diverter switches ( are always separate from the TR main tank 2- At the end of the video OT ( oil temperature gage) the red Needle is only a memory needle to show the highest temperature recorded by the OT. When the black needle ( showing actual temperature) moves up it will move the red needle along with it but when the temperature goes down the black needle will go down the red needle will stay at the maximum temperature the OT recorded so operator can see it during there inspection". Could you comment on this. And if he was correct: Are you looking to create a revised version of this video; or add an addendum that addresses these things one way or the other? Either way, the video was superbly done.. Thank you again.
Diverter switch compartment is separate which contains its own oil. During tap changing operations (raise/lower), selector switch contact is selected first and then diverter switch contact changes its position from odd to even or vice versa and desired tap is selected.
Great! Refreshed knowledge I had 35 years ago as a fledgling 11kV Authorized Person. Might have mentioned operationally that certainly oil cooled transformers can usually accept short term overload periods considering a 24 hour duty cycle. Finally, let's hope all "Pyrochlor" PCB oil has all been safely disposed of. Beware also that toxic brew was also used in early fluorescent light ballasts that might still be lurking in our sheds.
Out of all the comments made here this is one of great importance. The use of PCB's was widespread and there is undoubtedly many transformers lurking around with this free cancer toxic soup. It was also a very good thing to mention those old magnetic fluorescent lighting ballasts with the potted black toxic tar in them. I have come across many of these in the past. It helps to be wary of the potential dangers of these to help protect yourself from them and hope others see the importance of this. Excellent comment and Thank you.
As a new engineer in utilities, your videos are far better than anything I've learned on the job or in my schooling. For 9.99 euros i feel like I will be stealing from you. We get emails for courses all the time and they're always like $500 usd. Doubt my work will pay me back but for 9.99 it's worth it
Commercial & Resi Sparky here. Trying to teach myself about transformers and this was an excellent video. One suggestion would be to have a video on how they are installed & hooked up.
Good video and educational. There is a minor difference in terminology with respect to what the narrator called the limbs of the xfmr, whereas in the US we called those legs.
Great video indeed as many others have said. BUT there's only one major component that wasn't mentioned and I only know cuz I work in the utility industry. The CTs that are wrapped around the bushings. Very important piece to monitor the current flowing in and out of the transformer. And for protection.
Very nice introduction. A good supplemental video project could be made on Grids and Transport. Air/sub soil/sub sea line systems, TN´s, TT, IT and so.
I found your Francis Turbine and Induction Motor. There is still openings for making projects on Generators, Breakers & Relays, for a full basic intro set.
Glad it was helpful. Have a fully configured transformer on the website now and its quite cool to hide/show various bits. Pity it was not ready for this video really.
This is very educational. Do any (or can) any of these components out off an odor? I live near a substation and have noticed a foul odor that almost smells like old, spent oil. It is very bad smelling and pretty overwhelming.
At 14:25 you say in the left side the High Voltage bushing, but wouldn't the left be the Low Voltage as there is four of them meaning there is a Neutral?
Superb explanation! one question though: at 25:05, you explain that sometimes the 'transformer' is mounted outside the transformer tank, do you mean the 'tap changer' rather than the 'transformer' is sometimes mounted outside the transformer tank? Thanks!
you said that the high voltage side has the big bushings and the low voltage side has the small bushings although the high voltage side has the small amount of current and vice versa and another point , the high voltage side according to you has the neutral and i think it is in the low voltage side
Excuse me Sir, can you explain us about High series capacitance winding ? Which is used in power transformers windings, exactly in High voltage windings. With my best regards.
We have a factory that requires 6 MVA electric power , Can we use one large transformer and limit the fault current with NGR? our transformer is 11/0.4 KV
Correct. The red needle is also known as a drag needle which shows the highest temperature the top oil has seen. This needle can be reset to the ambient temperature. In this example, the alarm and trip values are set using the four "rings" seen below the dial. KB
the link to the oil analysis pdf is dead. Your comment about how the gasses can be an indicator of fault, would that pdf have discussed those characteristics? I'm super curious about that. Thank, sweet video.
If the primary and secondary voltages are the same and the vector grouping is identical, it will work. In fact, the active part should last longer as the cooling system is bigger.
A tank designed for higher power rating can be used for lower power rating. Quantity of oil will increase which will decrease oil temperature rise and winding temperature rise. So life of transformer will increase (refer IEC 60076-7).

Bigger the insulation the higher the voltage

Woo nice video
26:39 the red needle is just a max indicator for temperature
Correct. The red needle is also known as a drag needle which shows the highest temperature the top oil has seen. This needle can be reset to the ambient temperature. In this example, the alarm and trip values are set using the four "rings" seen below the dial. KB

@@savree-3d ohhh that sounds exciting. I'm such a nerd. Why do I can about transformer oil analysis LOL
I like this video!!!
if a small fault continues, in this case, as the volume of gas in the gas relay increases, will the transformer open
Buen trabajo.

What is the effect of using a 300KVA set of coils in a Tank designed for 500KVA 33/0.415Kv.
If the primary and secondary voltages are the same and the vector grouping is identical, it will work. In fact, the active part should last longer as the cooling system is bigger.
A tank designed for higher power rating can be used for lower power rating. Quantity of oil will increase which will decrease oil temperature rise and winding temperature rise. So life of transformer will increase (refer IEC 60076-7).
Can anybody mention here about pre Commissioning test of breather and off load tap changer?
Excellent explanation, consider my one like equal to 1000 👍. Upload similar for reactor, cap.bank and earthing transformer etc..,
which software do you use ?
