Why instruments are connected on low voltage side of the transformer while performing no load test?

since we need to get desired or rated voltage, so if it is connected in high voltage side of the transformer, voltage supply will be more, and hence the current will be more than the required amount. this is the reason why the instruments re connected at the low voltage of the transformer while performing no load test.

Why the transformer connected on inverter output?
A transformer is connected to the output of inverter in order to step up the AC voltage output.
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.
Type of transformers used in gas insulated substation?
Current transformer and voltage transformer . This transformers are actually measuring instruments which measures the quantity of current and voltage coming out of the substation.
How you can check load connected of transformer?
Measure the current and voltage on the secondary side.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
Why the transformer connected on inverter output?
A transformer is connected to the output of inverter in order to step up the AC voltage output.
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.
What type of voltage must be passed across a transformer?
A transformer must be connected to an alternating current (AC) supply of the correct voltage.
Can infinite voltage be given at transformer primary?
no, infinite voltage can't be given to the primary of the transformer....if the secondary is connected to the load, then over voltage will damage the load, if secondary is open circuited, then the infinite voltage can breakdown the transformer internal insulation,
In D.C supply the transformer is not connected why?
In a DC power supply a transformer is connected. The only time there would be no transformer used would be if the DC voltage wanted was 120 VDC. The transformer in the power supply is connected to 120 VAC on the primary side and the secondary side of the transformer is connected to either a half wave or a full wave diode bridge. The voltage out of the diode bridge will be the same output voltage potential as the transformer's secondary voltage but it will be a DC (Direct Current) potential.Reading the question in another way, transformers are not connected in a DC circuit. The reason being is that the transformer operates on a collapsing magnetic field. This field induces a voltage into the secondary side of the transformer. Since the DC circuit does not operate on the principle of a collapsing field except when the circuit is opened, the transformer would not operate as a transformer should..
What is the term for the transformer winding to which the load is connected?
The load is connected to the transformer's secondarywinding, while the primary winding is connected to the supply. The terms, 'primary' and 'secondary', do NOT relate to voltage levels.
Is there more current in the primary or secondary winding of a transformer?
The terms, 'primary' and 'secondary', describe how a transformer is connected and his nothing to do with which is the lower- and higher-voltage winding.The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. So, for astep-up transformer, the secondary winding is the higher voltage winding, whereas for a step-down transformer, the secondary winding is the lower voltage winding.For a loaded transformer, i.e. a transformer whose secondary is supplying a load, the higher-voltage winding carries the smaller current, while the lower-voltage winding carries the higher current.

Current transformer and voltage transformer . This transformers are actually measuring instruments which measures the quantity of current and voltage coming out of the substation.
How you can check load connected of transformer?
Measure the current and voltage on the secondary side.
What is the load side of a transformer?
The load side of a transformer feeds the device, such as a light or motor. It is the output of the transformer. The input, or line side, provides the voltage that is to be transformed, either up or down, to supply the load side.AnswerA transformer's primary winding is connected to the supply voltage, and the secondary winding is connected to the load.
What is an Earthed voltage transformer?
An earthing transformer provides a neutral in a delta connected system.
Does a transformer rectify the alternating current?
No, a transformer changes the ac to a voltage that the user requires. After that a rectifier can be connected to it to provide dc.
