Can you wire the load side of a transformer to operate the line side and get higher voltage?

Yes, it is called back-feeding and should only be done by a qualified electrician who has actual experience with this type of installation. Look up buck and boost transformer connections.

Is line voltage or phase voltage mentioned on transformer nameplate?
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.
Why might the unloaded output voltage of a transformer be higher than its rms of 12.6v?
Because the windings of transformers have resistance, the primary and secondary currents will cause voltage drops. To compensate for the drops, the transformer may have been designed to have a higher than specified output voltage when there is little or no output current. The no load output voltage typically is only slightly greater than the specified voltage. Before measuring the output voltage, measure the input (line) voltage. If it is not as specified for the transformer, calculate its effect on the output.
Does line to ground voltage always half the value of line to line voltage?
Line to Ground voltage = line to line voltage / 1.73AnswerIt depends what configuration is being measured. In the case of the secondary of a split-phase distribution transformer used to supply residences in North America, the answer is yes. In the case of a star (wye) connected secondary distribution transformer used to supply residences in Europe, no: the line to ground voltage will be as described in the first answer.
What is line interphase transformer?
interference line transformer display digit number in electerical device,such as generator it display amps rate&voltage etc.
What type of device is used to convert the high voltage on a feeder line to a lower voltage that can be used on the plant floor?
To convert the high voltage on a feeder line to a lower voltage that can be used on the plant floor you use a transformer.

What does inductive load effect on High Voltage transmission line?
the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.
Is tranformer used to increase or decrease AC voltage?
The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage. A step up transformer will transform a lower AC voltage to a higher AC voltage. The transmission of electrical power uses both of these types of transformers. From the generation station the voltage is stepped up to a very high transmission voltage and at the end of the transmission line it is stepped down to a voltage that consumers can utilize.

What is the function of step-down transformers?
The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage. A step up transformer will transform a lower AC voltage to a higher AC voltage. The transmission of electrical power uses both of these types of Transformers.

What is the main purpose of a transformer?
step up transformer output gives the high voltage which is useful for transmiission of electricity

interference line transformer display digit number in electerical device,such as generator it display amps rate&voltage etc.
What is the function of step up transformer?
The step-up transformer steps up the input voltage to a higher level so that it can be transmitted over a transmission line using smaller conductors. By the power law, power equals volts times amps, so you can achieve the same power with higher voltage and lower current, but the wire size is based only on current.On the other end, step-down transformers reduce the high voltage back to usable levels.
What do you mean by line in and line out in power system?
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.
Is transformer side interchangeable?
yes,we can change the transformer side in transmission line as use of high current or high voltage in output.
When step down transformer is activated what happens?
Step down transformer reduces high voltage of main power line and distribute it to desired level of voltage usable by residence or devices.
