A third winding - primary, secondary, and tertiary. The third winding is typically sized much smaller than the primary and secondary, and is very often a lower voltage; it can be used for stabilization, removal of 3rd harmonics, power factor correction injection (lower voltage inductors are cheaper), and station service.
What else can I help you with?
What is LV winding of a transformer?
For a step-down transformer, its secondary winding will be the LV winding. For a step-up transformer, its primary winding will be its LV winding.
What is the meaning of suffix YNaOd1 in vector group of transformer?
i understand that YNaOd1 represent an auto transformer with HV winding as wye connected and loaded tertiary. Please correct me if i am wrong.
How tertiary winding of power transformer acts as stabilizing winding?
in star-star neutral transformer at unbalanced load condition zerosequnce current will be flows in secondary side but this current can not be balanced by primary side because its not having neutral to circulate zerosequence current.due to this unbalance voltage will appeared in primary side but the tertiary delta winding allows circulate the zerosequence current so the primary voltage will get stabilized.
The insulation resistance of a transformer winding can be easily measured with?
It depends on the rated voltage of the transformer winding -are you talking about a 12-V transformer winding or a 400-kV transformer winding? Obviously, there is no one answer to your question!
What is winding transformer?
A winding is the name given each of the coils wound around the transformer's core. A basic transformer has two windings, termed the primary winding (connected to the supply) and the secondary winding (connected to the load).
What types names of windings does the transformer have?
The primary winding is connected to the supply. The secondary winding is connected to the load. A tertiary winding (if used) is a third winding, which may be connected in various ways.If the transformer is a three-phase transformer, then there are three common configurations: wye (also known as 'star'), delta (also known as 'mesh'), and zig-zag.
What is LV winding of a transformer?
For a step-down transformer, its secondary winding will be the LV winding. For a step-up transformer, its primary winding will be its LV winding.
What is a high voltage circuit primary circuit secondary circuit tertiary circuit?
The terms 'primary', 'secondary', and 'tertiary' winding has absolutely nothing whatsoever to do with voltage levels. The primary winding is simply that winding connected to the supply, while the secondary winding is that winding connected to the load. The voltages of these windings depend on whether you are dealing with a step-up or step-down transformer.

Do I need tertiary winding in a auto transformer with vector YNynO?
Depends, do you need to connect auxiliaries/generator/capacitor/reactor to tertiary? If not you may consider to not to use tertiary. The 3rd harmonic current will become an issue then. The phase to ground Isc will be lower.
The primary winding in a transformer is connected to the what?
The primary winding of a transformer is connected to the supply, while the secondary winding is connected to the load.
What type of transformer has only a single winding?
the auto transformer is the one winding transformer. it ismaily used in practical purpose.
How could you convert step up transformer into step down transformer?
Injecting power into the higher voltage winding of a transformer will make it act as a step down transformer; injecting power into the lower voltage winding will make it act as a step up transformer. A transformer can be used both ways.
Is there more current in the primary or secondary winding of a transformer?
The terms, 'primary' and 'secondary', describe how a transformer is connected and his nothing to do with which is the lower- and higher-voltage winding.The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. So, for astep-up transformer, the secondary winding is the higher voltage winding, whereas for a step-down transformer, the secondary winding is the lower voltage winding.For a loaded transformer, i.e. a transformer whose secondary is supplying a load, the higher-voltage winding carries the smaller current, while the lower-voltage winding carries the higher current.
