No Load & On Load Tap Changer In Transformer

A tap changer is a mechanism in transformers which allows for variable turn ratios to be selected in discrete steps. Transformers with this mechanism obtain this variable turn ratio by connecting to a number of access points known as taps along either the primary or secondary winding.

Best Explanation. Thanks a lot!

[@yugandharkalimireddy9019]

I think most of the on load tap changers employe impedance circuit to limit the short circuit during movement of divertor switch I hope u may do a video on that Good explanation 👏👏

[@shyamsundarpradhan5521]

Very nice explanation

[@tauhidansari8272]

A good effort to explain the use of tap changer, unfortunately the way the operation of diverter is explained in this video is not in line with the available tap changers today. It is kind of mix of reactor type tap changer into in-tank diverter. Which is mostly resistance type. Unless a vacuum bottle is used for breaking circuit, every tap changer compartment, do arc. This is the reason, diverter is housed in separate tank. The divert only changed from even to odd and selector selects the tap. If interested I can explain why I am saying so that you can correct the information in this video. I have no interest stealing your show so I can support you and you explain to audience. Overall it is good effort.

good job

[@AKSHAYKUMAR-xx2ed]

Very Informative Video. I have a question, how is an On Load Tap Changer defined thorough its specifications ? For example a Power Transformer would have Technical Specification in Terms of power ratings in KVA or MVA and Voltages on High Voltage Side and Low Voltage Side as 230/13.2 KV and 24/31/37 MVA . Similarly how do you define an OLTC ? Also is it possible to use same OLTC for a Power Transformer of rating specifications 230/115 KVA and 170/238/300 MVA and another Distribution Transformer of Power Rating 230/13.2 KV and 24/31/37 MVA ? If so, would it not be extremely cost inefficient to use same OLTC for a smaller distribution transformer ? Would be optimum ratings (specifications) of OLTC for both type of Transformers mentioned above ?

Your explanation is good.. But draw a proper diagram so we can use this diagram in exam Paper.... Bcuz proper diagram indicates full mark

[@harishgunda5315]

Please explain what is make in break in contact's how its operates can u explain

[@surajpanda5615]

Sir please explain at the time of tap changing how another path create.... And how any disturbance not occur in this time

[@krishnadakhanedakhane9653]

VOLTAGE DEPEND ON TURN SO HOW IS POSSIBLE OUT PUT VOLTAGES ARE INCREASE BY DECREASING PRIMARY TURN

[@tauhidansari8272]

By decreasing the primary turn, it’s increases the volt/ turn, that increases the secondary voltage

[@sourabh669]

why 9a, 9, 9b this three tap positions are used in 9th tap in a 132kv transformers

[@yashucutebabu4751]

These tap position are basically an arrangement of reversal switch which is used to single winding reuse once again for tapping in reversed direction...means this will save the cost of the whole winding as we used it two times for 1 to 8 taps in one direction of winding and for 9 to 17 taps of windings in reverse direction by using reversal switch for a power transformer...

how many tap changer in transformer

[@SmileandLearnflyfree]

Tap changer can be on one side or on both sides as required

[@kamalpandey1761]

Please state off-circuit type tap changer instead of no-load tap changer.

[@baburamabadhran1437]

They also have another name as Deenergised tap changer.

No

@@michustinyworldsmagic7842 what is the critical advantage of the tap changers. Also what is the value addition created by Off circuit tap changer switches

[@tauhidansari8272]

@@baburamabadhran1437 off circuit tap changer helps setting up to the tap corresponding to available voltage. Once in service, the off circuit or de energized tap changer is hardly operated for the rest of transformer life. There was effort in IEEE to remove the need but not successful
