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.
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.
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.
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.
interference line transformer display digit number in electerical device,such as generator it display amps rate&voltage etc.
To calculate the voltage ratio of a three-phase transformer, you divide the primary voltage (Vp) by the secondary voltage (Vs). The formula is expressed as Voltage Ratio (Vr) = Vp / Vs. This ratio indicates how the transformer steps up or steps down the voltage between the primary and secondary windings. Additionally, ensure the voltages are measured in the same phase configuration (e.g., line-to-line or line-to-neutral) for accurate results.
The purpose of a doorbell transformer in a home electrical system is to reduce the voltage from the main electrical line to a lower voltage that is safe for the doorbell system to operate.

the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low 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.

step up transformer output gives the high voltage which is useful for transmiission of electricity
The purpose of an old doorbell transformer is to reduce the voltage from the main electrical line to a lower voltage suitable for powering a doorbell. It functions by stepping down the voltage to a safe level for the doorbell to operate without causing damage to the doorbell or the home's electrical system.

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.
