What else can I help you with?
Why transformer is used?
A transformer used to step up or down the value of voltage.
How do you improve the ir value of the transformer?
Moisture entered inside the transformer coil may cause loss of IR value. IR value can be increased by removing the moisture. Keep the transformer in a hot air chamber for sufficient time to vaporize the moisture.
What is the ampere range value of transformer?
This typically has to do with how many amps you can safely pull from the secondary of the transformer.
What is a set down transformer?
A stp-down transformer steps voltage down from a high value to a low value. Transformers only work with AC.
What is the full load loss of a 630 kva distribution transformer?
Much to my dismay i found its an experimental value, depends on type of core, cooling tech, resistance of wiring etc.
What is the resistance of the secondary of a 24 volt transformer?
The resistance of the secondary of a transformer depends on the wire gauge and length of wire used in the winding. Typically, the resistance of the secondary winding of a 24 volt transformer can range from a few ohms to tens of ohms. It is best to measure the resistance using a multimeter for an accurate value.
Why the winding resistance of transformer is not sufficent when it is used in dc supply?
It is.AnswerA transformer is designed to operate with an AC supply voltage, not DC -in fact, it cannot operate with a DC supply voltage.Opposition to the flow of alternating current is made up of resistance and reactance. Resistance depends upon the length, cross-sectional area, and resistivity of the transformer winding conductor. Reactance depends upon the inductance of the transformer winding and the frequency of the supply voltage.Because a transformer winding is highly inductive, its reactance is very much larger than its resistance, and is more than sufficient to limit the AC current to a value that will not overheat the winding conductor. However, if you supply the transformer with a DC voltage that is equivalent in value to its AC rated voltage, the low value of resistance will allow a very large DC current to flow -large enough, probably, to overheat the conductor insulation, possibly causing it to break down and cause severe damage to the transformer.
What is the difference between a transformer and a rectifer?
A transformer is used to change the value of a voltage applied to the transformer's primary winding to a different voltage value taken from the transformers secondary winding. A rectifier is used to change an alternating current value to a direct current value.
What are the conditions for operate the three phase transformer?
The BDV value of the transformer oil should be above 50kv winding resistance value should me minimum depends upon the KVA Of trans earthing should be provide for the trans air should be release inside of the tranformer insulation level should be check to operate the transformer these are all the initial condition to operate the trans
What is the Al value of transformer?
AL means transformer core property
What will happen if a new branded 132KV transformer is charged at the IR value of 150Megaohm between HT winding and Earth remaining IR values being found infinity?
Sir I am Imran khan in nepal my problem is 6000KVA Step down Transformer is not charging. Transformer Pri- 33000V /105A Sec- 6900V / 502Atransformer all test (open & short circuit ) good . but problem is HT(IR)= value this time IR value 50M ohmBefore 3days HT(IR) = value is 7000M ohm suddenly start Transformer result is Transformer not charging & HT(IR) value is down 50M ohm.

What happens when DC supply applied in to the power transformer?
we cant give dc supply to a transformer because it will have some constant frequency to work..Dc is not having any frequency component.Comment:Nothing will happen. Transformer works on the principal of electromagnetic induction were an alternating magnetic flux of the primary winding links up with secondary winding via the core. An emf will then be induced in the secondary winding if it's cut by the alternating flux. Only AC can attain this. DC does change directions and hence it won't effect anything.AnswerIf the value of d.c. voltage is equivalent to the transformer's rated primary voltage, then it's very likely that the primary winding will burn out as it has a very low resistance and the resulting current would be high.
