Not clear what your question is. First of all, circuits are not classified as DC and AC. Circuits are what they are, and you can apply either AC or DC to any circuit. However, considering a circuit that was designed only for use with DC applied. Still your question is unclear. What is transformer action? "Transformer Action" happens in a transformer.

What multimeter readings set to measure resistance indicate an open circuit and short circuit in the primary and secondary windings of a mains power transformer. And what readings show good?

You cannot use an ordinary multimeter to assess the difference between a normal power transformer winding and a shorted power transformer winding. You need a Q meter and/or to power it up at a reduced voltage with limited current to see what happens. Note that a shorted power transformer is capable of exploding, so you need to take appropriate safety precautions.


What is the two differences between AC and DC?

Alternating current is bi-directional current that changes its direction frequently in circuit wheras Direct current is uni-directional current that does not change its direction when flowing in a circuit. In transformer(be it step up or step down) ONLY AC is used.This is because the direction keeps on changing so due to this the magnetic field also varies.So this leads to electromagnetic induction and there by this is the principle of a transformer. DC cannot be used in this because the direction does not change and due to this there is no change in the magnetic field and thereby electromagnetic induction does not take place


Why would you use a three phase transformer in place of a single phase transformer?

the necesscity of two three phase transformers operating in parallel are as follows...if the one transformer fails to give supply,then another transformer can be used in parallel and hance,continuity of supply can be maintained.one transformer can be easily take out from the supply for repair & maintanance.if the load on the substation increases beyond the rated values of transformer, then another transformer can be used to share rhe load of the substation.


Why it is necessary to disconnect the load when change the tap?

when the load is connected to draws some current. while changing the tap of the transformer the tappings related to the winding is changed , so the load current affects the transformer. hence while changing the tap it should be noted thatAnswerThere are two types of tap-changing mechanism -'off-load' and 'on-load'. Off-load tap changers physically disconnect the winding when changing from one tap setting to the next. Accordingly, the circuit is temporarily broken, and dangerous arcing will take place if the transformer is energised. Therefore off-load tap changers require that the transformer is disconnected while the mechanism is operated.On the other hand, 'on-load' tap changers use a mechanism which incorporates a 'make before break' contact arrangement, ensuring that no break is made in the circuit as the mechanism moves from one tap setting to the next, enabling it to operate with the transformer energised and supplying load. On-load tap changers are usually automatically operated, although this feature can be overridden and operated manually.


Conversion of 2-winding transformer into auto transformer?

Yes, you can use a mutual (2-winding) transformer as an autotransformer, by connecting the two windings in series. For example, if you have a 240:120 V transformer, connecting the two windings in series and supplying the 240-V winding with 240 V can give you a secondary voltage of 360 V. But you must take into account the polarity of the transformer, and realise its capacity will change.

How to calculate short circuit protection for transformer?

don't overload it, have a look on the transformer their should be an input voltage and an output voltage if take fails just try and see if u can overload it when you do try and figure out the voltage and get a new transformer;)!!!!!


What does short circuit current available mean?

If you take a power source like a dc battery or AC transformer secondary winding and connect an ammeter directly across these power sources you can read the short circuit current available from that source. This gives a measure of internal resistance of the battery or the available wattage of the transformer.

Does led lighting require a transformer per light or one per circuit?

One transformer should feed several led's in parallel, but you have to work out how much current each one will take, total it up, and then get a transformer with the correct output voltage and that can supply the total current. Don't exceed the transformer max current or it may fail through overheating
