The ratio of windings between a primary and secondary in a transformer govern the output voltage. Multiple taps are connections to various points in the coil effectively changing the winding ratios to get multiple voltages from the same transformer. Taps can be on the primary, secondary or both to provide a more versatile transformer.

What is off load tap change?
Tap changer is a device that is used to change the secondary voltage on transformers. It is normally on the HV winding of the transformer. Off load tap changer is designed to change the taps only when the transformer is not charged, while on load tap changer is capable of changing the tap on load too.
Why are some house currents 130 volts instead of 120 volts?
It depends on the local utility power company and the the neighborhood transformer taps used. It also depends on how far away the transformer is from the house. There is a voltage drop depending on the size and length of wire. It sometimes is 120v, 125v, 130v or anywhere in between. It doesn't make much difference.
What is the output voltage across the secondary of a center-tapped transformer rated at 9-0-9?
If measured on the two outside taps the output will be 18 volt. Measured from the center tap to either of the outside tap will give a reading of 9 volts.
What is center tap transformer?
Center tap transformer is the such kind of transformer that is made to a point half way along a winding of a transformer.
What is the application of pluse transformer?
why should we use pulse transformer rather than ordinary transformer
What is uses of tapped coil?
If question is about a transformer's tapped coil then the taps are a way of getting different voltages from one transformer. The end of the transformer's coil is the common point and the taps to this common point will give different voltages depending on where in the coil the taps are taken from.
How can a step down transformer which is transforming 450 volt in the last tap be changed to 415 volt?
The instruction for changing the taps on a transformer can be found on the transformers nameplate. These taps will be on the primary side of the transformer. Each tap position will state what the voltage will be on the output when the individual tap is selected.
How does the voltage varies through tap chinging of a transformer?
Voltage varies through tap changing of a transformer because the different taps connect to different points on the winding, with the result that use of different taps constitutes use of different turns ratios.
What are the basic components of a transbsformer?
A transformer has input and output connections, a primary winding with or without taps, and a secondary winding or windings with or without taps. It also has a core and appropriate wrappings, and it sometimes has a housing.
What is the difference between an ordinary transformer and a center-tapped transformer?
An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.
Are a tapped transformer and a step-down transformer the same?
Transformers can be used in either step-up mode or step down mode, they are just as efficent connected either way. Most large transformers have percentage "taps" to allow voltage corrections up or down by about 15%.
On what websites can you get taps trumpet?
taps
What are the names of the three taps in a set of taps?
Hand TAPS are usually made in sets of three. Taper, Plug, Bottoming taps.
What is off load tap change?
Tap changer is a device that is used to change the secondary voltage on transformers. It is normally on the HV winding of the transformer. Off load tap changer is designed to change the taps only when the transformer is not charged, while on load tap changer is capable of changing the tap on load too.
What are cemetery taps?
Cemetery taps are military taps buglers that were played at military cemeteries.
