A transformer is used to step up (increase) or step down (decrease) an alternating voltage with very little loss of energy.
At the power station end, it steps the generated voltage up to a very high level for transmission. At load centres, it steps down the transmitted voltage for distribution.
A transformer. A small example is the coil in a motorcar. A transformer, in a power line, only changes voltage in one direction under normal usage. At distribution voltages, about 8360 VAC, the voltage is monitored by a regulator. A regulator either increases or decreases the voltage automatically to insure the desired voltage is steady. This regulated voltage is then fed to Transformers to provide customers with a regulated voltage at the desired voltage.
the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
step up transformer output gives the high voltage which is useful for transmiission of electricity
depending on the amount of the load of transformer as well as the power factor of it, there is a transformer specific voltage drop at its terminals, due to the internal impedances. The on-load tap changer can / will be used to compensate this voltage drop or rise.
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
A transformer can perform this function.
Step down transformer reduces high voltage of main power line and distribute it to desired level of voltage usable by residence or devices.
A transformer changes the electricity from one voltage to another, which allows a high voltage power line to be converted down to a voltage suitable for home usage.
It depends how they are connected. If they are connected between line conductors then they are measuring line voltages. If they are connected across phases then they are measuring phase voltages.

The device that increases or decreases the voltage impressed across a power line is known as a voltage regulator. A voltage regulator is a type of transformer where the primary and secondary turns ratio are fairly close; one (primary or secondary) often has a tap changing ability to add or remove several windings, allowing more dynamic control of voltage.
In Europe, low-voltage three-phase distribution is by means of a four-wire system (three line conductors and a neutral) supplied from a wye-connected transformer secondary. In North America, low-voltage is supplied from a delta-connected transformer secondary, one phase of which is centre-tapped and earthed (grounded). The single-phase supply to residences is then supplied by that particular phase, giving 240 V line-to-line and 120 V line-to-neutral. You can tell if you have a delta power when the phase voltage is equal to the line voltage and that you have a star power when the phase voltage =root 3(THE LINE VOLTAGE).
It is the same as phase to neutral. As the neutral is earthed at the electricity suppliers transformer.
A1: Usually this is in reference to a transformer that either steps up or steps down the Line Voltage. For example if your house line voltage was 120 VAC and this voltage was attached to the input (Primary) or a transformer, the output side of the transformer might step up the voltage to 240 VAC. This would be called line out voltage on the secondary of the transformer. A2: In case the question was related to audio signalling and amplification, Line In and Line Out are low level inputs and outputs of audio signals, often using RCA phono jacks, such as what is connected between a tape deck or CD player and your mixer or amplifier with coaxial cables.
