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.

When working on a current transformer the secondary windings must be?
When working on a current transformer the secondary windings must be shorted. <<>> Properly loaded
What is core type and sell type transformer?
Core transformer and shell transformer - it has a one window. - it has a two windows. - less mechanical protection - better mechanical protection to the coils. to the coils. -windings encircles the core. - core encircles the winding. - cylindrical windings are used. - sandwich type windings are used. - it is easy to repair. - it is not easy to repair.
If a step-up transformer is to increase voltage it needs?
A step-up transformer needs more turns on the secondary windings than on the primary windings to increase the voltage.
Load test on single phase transformer?
The dc tests that can be done on a transformer are to measure the resistance of each windings and to measure the insulation resistance between the windings and between each winding and the transformer case.
What causes a low voltage in the transformer?
If this refers to a wire wound transformer, as it sounds then there is likely only two possibilities : the input voltage has dropped prier to entering the primary windings or there is a short in the windings some where within.The only other possibility I can think of is : This is a trick question and the transformer is a step down transformer.
Which types of windings used in transformer?
Clarify your question. What do you mean by 'type' of winding?
Why induction transformer called rotating transformer?
Transformer has windings
Is 3 phase star transformer has more winding than delta?
The # of windings in a transformer are based on the primary and secondary voltages the transformer is rated for not the way the windings are connected.
When working on a current transformer the secondary windings must be?
When working on a current transformer the secondary windings must be shorted. <<>> Properly loaded
What is the three phase transformer?
it has three primary windings & three secondary windings.
What is transformer tank?
The container the transformer core and windings are placed inside is the tank.
What is core type and sell type transformer?
Core transformer and shell transformer - it has a one window. - it has a two windows. - less mechanical protection - better mechanical protection to the coils. to the coils. -windings encircles the core. - core encircles the winding. - cylindrical windings are used. - sandwich type windings are used. - it is easy to repair. - it is not easy to repair.
Is it a step up or a step down a transformer has 20 primary windings and 100 secondary windings the secondary voltage is 25v?
If a transformer has 20 primary windings and 100 secondary windings, it is a step up transformer. If the secondary voltage is 25v, the primary voltage will be 5v, because the turns ratio is 20 to 100, or 1 to 5.
How do you know if transformer has copper or aluminium windings?
They have both.
If a step-up transformer is to increase voltage it needs?
A step-up transformer needs more turns on the secondary windings than on the primary windings to increase the voltage.
If a transformer has 20 primary windings and 100 secondary windings and the secondary voltage is 25 what is the primary voltage?
Transformer step-up/step-down voltage is turns-ratio, so if a transformer has 20 primary windings and 100 secondary windings (a turns-ratio of 1 to 5) and the secondary voltage is 25, then is the primary voltage is 5.
What are the physical parts of transformer?
Physicially it has transformer tank, conservator, bucholz relay , windings, oil
