If a DC supply is connected to the incomer of a transformer, you effectively have a short circuit, because the DC impedance of a transformer (actually, any inductor) is quite low. You will blow something.

What types names of windings does the transformer have?

The primary winding is connected to the supply. The secondary winding is connected to the load. A tertiary winding (if used) is a third winding, which may be connected in various ways.If the transformer is a three-phase transformer, then there are three common configurations: wye (also known as 'star'), delta (also known as 'mesh'), and zig-zag.


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 load is always connected to secondary of transformer?

b'coz at the secondary side large amount of current flow by recarding of active component or other ckt. which is connected to the secondary side so that ckt. is not damage or burned by flowing large amount .. load is connected at the secondary side .AnswerThe 'primary' winding of a transformer is, by definition, whichever winding is connected to the supply, whereas the 'secondary' winding is whichever winding is connected to the load. This does not mean that a load MUST be connected to a transformer, as it will work 'off load' -that is, with no load connected- without any harm.


Why ghost power acting on a circuit?

Ghost power may be acting on a circuit if it has a capacitor or transformer connected. This will supply power long after the input has been disconnected.


A doorbell is connected to a 110v supply but it operates only about 12 v-14 v. What kind of transformer does it have?

The doorbell uses a step-down transformer, which reduces the higher 110V supply voltage to the lower operating voltage of 12V-14V. This transformer is designed specifically for doorbells and similar low-voltage devices, ensuring safe and efficient operation while allowing the doorbell to function correctly.

What will happen if transformer are connected to dc supply?

It will get core saturation


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.


What is winding transformer?

A winding is the name given each of the coils wound around the transformer's core. A basic transformer has two windings, termed the primary winding (connected to the supply) and the secondary winding (connected to the load).


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 happens to a 220v 50hz stereo amplifier when connected to a 220v 60hz supply?

Nothing happens. The stereo has a transformer that converts the power to DC, and 50 or 60 Hz input makes no difference.


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.


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 are the primary winding and secondary winding of a transformer?

The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. The terms, 'primary' and 'secondary' are unrelated to voltage levels.


What is stepup transformer?

A step-up transformer produces a voltage across its secondary winding which is higher than its primary winding. The secondary winding is connected to the load, while the primary winding is connected to the supply.


Could three-phase 4-wire supply be obtained from balanced two-phase supply by means of Scott connected transformer?

Yes


Why in no load test transformer is connected on low voltage side?

A no-load test is done with the normal supply connected in the way the transformer is intended to be used. It is also known as an open-circuit test to distinguish it from a short-circuit test, and its purpose is to measure the power loss in the iron core of the transformer and the no-load current drawn from the supply.
