Q:How to understand the secondary side of the transformer

The transformer consists of iron core (or core) and coil, the coil has two or more than the winding, which connected to the power supply winding called the primary coil (a test), the rest of the winding called secondary (secondary side). The basic principle of the transformer is the principle of electromagnetic induction, now single-phase double-winding transformer as an example to illustrate its basic working principle: When the primary winding with voltage U1, the current I1 flow, in the core to produce alternating magnetic flux , These magnetic flux known as the main flux, in its role, both sides of the winding were induced potential E1, E2. Transformer two sets of coil turns are N1 and N2, N1 for the primary, N2 for the secondary. In the primary coil plus an AC voltage, the secondary coil will produce both ends of the induced electromotive force. When N2> N1, its induction The electromotive force is higher than the primary voltage. This transformer is called a step-up transformer: when N2 <N1, its induced electromotive force is lower than the primary voltage, which is called a descending transformer. Primary secondary voltage and coil The number has the following relationship: U1 / U2 = N1 / N2 Suppose that n is the voltage ratio (turns ratio). When n <1, then N1> N2, U1> U2, the transformer is a step-down transformer, otherwise it is a step-up transformer.

Q:80 kilowatts of electrical appliances need much transformer?

The selection of the transformer is based on the current. 80KW electrical current is 210A210 times (380 multiplied by 1.732) 138kva above the transformer can

Q:What is the meaning of the transformer 'turns ratio'? what's the effect?

The turns ratio of the transformer is the ratio of the transformer, that is, the ratio of the turns of the original coil and the secondary coil. Role: reflects the original transformer, vice coil voltage RMS ratio. In the case where the no-load current is negligible, the magnitude of the original and secondary coil current is inversely proportional to the number of turns. transformer Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.

Q:how transformer came to know that it has to draw lagging current during summers

The transformer itself is inductive, as others have said, so it will always appear as a lagging load. Now, in the summer, most people are using their air conditioning systems, which are quite inductive because they're essentially just motors. So, the load attached to the transformer could be a good bit more inductive than in other seasons.

Q:actually we are trying to make a dc transformer,in which we want variable dc voltage at primary sidewe are doing this by using a rheostatwhich will change the value of current continously thus accordingly the value of voltage varyare we thinking right or wrong????

A dc transformer is impossible.Voltage transformation happens when there is an operating frequency and dc circuits has zero frequency. You may use voltage divider network for voltage reduction.

Q:i want what does a transformer exactly do and not how it works

Transformer is used to step up or step down an AC. Its consist of two winding, that is primary winding and secondary winding.Its operation depends on electromagnetic induction between two stationary coils and a magnetic flux of changing magnitude and “polarity . Below is the link, that got further explanation. Hope it can help u. :-)

Q:i want to know the actual lyrics for the Transformers theme that was re-covered by Mute Math. i heard that they changed some of the lyrics but i would like to know the exact changes, thanks.

Whoa she just gave you the best answer!!

read material regarding transformers Not just once but say 5 times, till you understand what is said. the transformer has copper loss due resistance of primary and secondary. It has additionally iron loss. The equivalent circuit is a sort of representation that brings in these losses. generally you can apply a low voltage to primary till shorted secondary has a current equal to less than rated current. These measurement details are given. Similarly open circuit measurement details are available. With understanding of how the rest can be calculated using worked examples in texts, you can solve it yourself. attempt this See Lee's book on transformers or schaums series on electrical engg.

Q:1.Is there going to be a Season 4?2.If there isn't,then is there going to be a new Transformers series?

Transformers animated ended last Saturday with Endgame part II. It was ended because of the movie coming out and Hasbro wanted to focus on movie merchandise. There's been some talk of maybe it starting up again after the movie or even a new cartoon.
