A transformer does not use a filter.
You may be asking about the use of a filter in a power supply.
A power supply uses a filter to change pulsating DC from the rectifier into smooth DC for the circuits that the power supply powers.

What effect does the series resistance of a capacitor used in a capacitor filter have on diode current and ripple voltage compared with an ideal capacitor of no resistance?
The effective resistance of the capacitor reduces the ripple current through the capacitor making it less effective in its function of smoothing the voltage. But if the capacitor filter is fed by a transformer and diodes, the resistance of the transformer exceeds that of the capacitor.
What difference's between potential transformer and voltage transformer?
Both are same. This is an instrument transformer used for metering & protections.
What is the name of the transformer that reduces the voltage?
a step down transformer is used to lower the voltage from the powerlines into your home. a common slang term for this type of transformer is a pole pig.
Can you use a transformer to convert modified sine wave to pure sine wave?
we cannot use transformer because transformer cannot change frequency . . .
What is the definition of audio-frequency transformer?
An audio frequency transformer is a transformer designed to operate in the range of frequencies audible to the average human. This range is generally accepted to be from 20 Hz to 20,000 Hz. The usual purpose of an audio transformer is to match impedances between circuit sections. For example: between a microphone and the input of an amplifier, (input transformer), or between the output of an amplifier and the loud speaker. (output transformer).
What kind of a filter do you need to stop static in a FM radio in a shop that has neon lights?
You probably need an RFI (Radio Frequency Interference) filter either between the neon lighting transformer and the wall plug, or a transformer with a built-in RFI filter.
Why is intermediate frequency transformer used in amplitude modulation?
used as a adjustable band pass filter...
How do you decide transformer oil filteration required?
When the water content in the oil in the Oil rises up to or more than 2% than it is needed to replace the transformer oil or filter it.
Is it necessary to filter new transformer oil?
Probably not. Transformer oil is generally highly purified mineral oil, so unless you're getting it from shady sources, you should be fine.
What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a full rectifier circuit with a filter capacitor?
25.46V assuming output of transformer is pure sinewave.
What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a full-wave rectifier circuit with a filter capacitor?
25.46V assuming output of transformer is pure sinewave.
What purpose of oil filter in transformer?
To remove impurity particles which could reduce the insulation property of the oil as well as that of the windings.
What effect does the series resistance of a capacitor used in a capacitor filter have on diode current and ripple voltage compared with an ideal capacitor of no resistance?
The effective resistance of the capacitor reduces the ripple current through the capacitor making it less effective in its function of smoothing the voltage. But if the capacitor filter is fed by a transformer and diodes, the resistance of the transformer exceeds that of the capacitor.
Can a person use a transformer to convert modified sine wave into pure sine wave for off grids electrical suppy system?
A pure sine wave does not have any harmonic components beyond the fundamental. A transformer, if chosen carefully, could act as a low pass filter (removing the harmonics), but this is overkill. It would be better to develop a filter to do this.
What is a half transformer and a half transformer?
a hole transformer
Why induction transformer called rotating transformer?
Transformer has windings
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
