Yes it can if it's connected in a push pull reconfiguration
Basically the characteristics of a transformer depends on the impedance(resistance) and on the coupling of its primary and secondary coils. The impedance of a coil depends on the frequency, as the frequency increases you need less volume of iron core and less number of turns in the coil for a given impedance, then reducing the size of the transformer.
Impedance (Z) voltage is the amount of voltage applied to the primary side to produce full load current in the secondary side. It is usually listed on the transformer nameplate, expressed as a percent, and measured by conducting a short circuit test.
Generally speaking, equivalent circuits are used to simplify a complex circuit into terms that are solvable with known relations. For example, in a transformer equivalent circuit you can account for winding losses and flux leakage with a series resistance and reactance on the primary side. Core losses can be modeled similarly with a parallel resistance and reactance on the primary also. Essentially when reflecting/referring an impedance to the primary side of a transformer, you are just seeing what the secondary impedance "looks like" to the primary side. Since the secondary impedance will determine the load on the primary, it is helpful to know how to relate it in terms of the primary so as to calculate the current flow in the primary due to the load on the secondary.
Winding copper losses of a transformer can be measured in a short circuit test of a transformer. Impedance voltage is given to the primary and the secondary is often shortcircuited. (some times the reverse is done of this). Full load currents are made to flow in both primary and secondary circuits. This current flow heats up the 2 windings of the transformer. Power consumed at this time gives the transformer copper losses.
The incoming voltage from the source to the transformer is called primary voltage.
Inherently, the actual impedance seen at the secondary voltage will be different than that seen at the primary voltage. To make things easy, we use symmetrical components, where transformers are reduced to a p.u. (per unit) impedance. 100 x p.u. is equivalent to the percentage impedance you are referring to. When converted to per unit, a transformer has one impedance, not two, so it does not matter whether you are looking through the transformer from the secondary or the primary.

The transformer impedance is the amount of voltage applied for transformer during the load test.Answer.I really don't agree with the answer given by the previous user.Impedance is the total vector opposition offered by the transformer to the flow of current i.e the vector sum of its pure resistance (R) and it's inductive reactance (XL). http://en.wikipedia.org/wiki/Electrical_impedanceAnother AnswerThe 'impedance' of a transformer is usually expressed as a 'percentage impedance', which is defined (perhaps rather confusingly!) as the ratio of the primary voltage that will result in the full rated current flowing through the secondary, to the rated primary voltage.

The term, 'percentage impedance', is a little misleading, as it is defined as 'the value of primary voltage that will cause rated current to flow in the secondary winding, expressed as a percentage of the rated primary voltage'. So, the test is carried out as follows: the secondary winding is short-circuited through an ammeter capable of reading the rated secondary current. A variable voltage is applied to the primary winding. The primary voltage is gradually increased until the ammeter indicates rated secondary current. That primary voltage is then expressed as a percentage of the rated primary voltage -and that value is the transformer's 'percentage impedance'.
The basic principle of current transformer is same as that of the power transformer. Like the power transformer current transformer also contains a primary and a secondary winding. Whenever an alternating current flows through the primary winding alternating magnetic flux is produced, which then induces alternating current in the secondary winding. In case of current transformers the load impedance or "burden" is very small. Therefore the current transformer operates under short circuit conditions. Also the current in the secondary winding does not depend load impedance but depends on the current flowing in the primary winding.
In electrical engineering, the percentage impedance of a transformer is the voltage drop on a full load, which is expressed as a percentage of the specified rated voltage. It's measured by conducting a short circuit test.
When the primary and secondary voltages are the same the transformer is being used for isolation. The secondary side will have galvanic isolation from the primary side. The purpose of the is to protect secondary load if a fault occurs on the primary side. The impedance of the transformer will limit the fault current on the secondary which should save equipment.
The leakage reactance is one of the components of the reactance in the input impedance that is there when the load impedance is purely resistive. The leakage reactance is due to flux that fails to link both the primary and the secondary windings.

(some times the reverse is done of this). Full load currents are made to flow in both primary and secondary circuits. This current flow heats up the 2 windings of the transformer.

No. A CVT (capacitor voltage transformer), like an voltage transformer, has a high primary impedance. the connections of a CT require the high voltage current to pass through the primary winding. This would result in significant loading of the circuit in question, at least until the CVT cooked.
