What is the different between et up and set down transformer?
the difference between a step up transformer and a step down transformer is that, in a tsep up transformer, the voltage secondary is greater than the primary side but in a step down transformer, the voltage secondary is lesser than the primary side
Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
What the transformer oil transformer provides?
Significantly-better cooling and insulation than air. This means that the transformer can operate at higher power ratings than an equivalent air-cooled transformer, and its internal electrical components can be much closer together, giving an oil transformer a much smaller footprint so it takes up far less space in a substation.
If you have a 1000kva transformer than can you work on that transformer?
No. From what you're saying you're taking the input to the 2kV transformer in a microwave and replacing it with a 1MW input. The transformer will burn in milliseconds of power. <<>> The installation and maintenance of a 1000 KVA transformer can be worked on in a de energized state. To do so live could be extremely dangerous at any voltage.
What is difference betweena step up transformer and step down transformer?
The difference between the two transformers is the coil ratios between the primary and secondary windings. A transformer that increases voltage from primary to secondary has more secondary winding turns than primary winding turns and is called a step-up transformer. Conversely, a transformer with fewer secondary windings does just the opposite and is called a step-down transformer.
What are applications that use a toroidal transformer?
Toroidal transformers produce less radiated noise (50 or 60 Hz hum) and generally are smaller and lighter than conventional laminated steel core transformers.
What is the difference between Auto transformer and Power transformer?
An auto transformer has one winding with the output being tapped at some point and therefore has no isolation between primary and secondary. This may make it unsafe or illegal in some applications. A common power transformer has separate windings.
What is the Difference between conventional transformer and toroidal transformer?
Conventional transformers have rectangular cores, whereas toroidal transformers have circular ('toroid' means 'circular') cores. The windings are placed around conventional cores by removing the top 'yoke' (horizontal member) of the core, making them easy to manufacture. For a toroidal transformer, however, the windings have to be actually wound around the core, making them much more difficult and, therefore, expensive to manufacture. Toroidal cores have less magnetic leakage than conventional cores, but are limited to small applications (e.g. hi-fi amplifiers, etc.), whereas conventional cores can be manufactured to any size.
What is the purpose of auto transformer?
Helps with the starting of large electric motors.AnswerAn autotransformer is a transformer with a single winding, rather than two separate windings. It can be used as a step-up or as a step-down transformer, provided there is no requirement for electrically-isolating the secondary circuit from the primary circuit.
What is inversion microwave cooking?
Inverter microwaves (used in inversion microwave cooking) involve a newer technology than conventional microwaves, and produce more even cooking and defrosting. They replace the capacitors and transformers of conventional microwaves with circuit boards, so they are also much lighter and can contain more cooking space than conventional microwave ovens.
What benefits do aspheric lenses offer?
Aspheric lenses are very good for individuals with a strong eyeglass prescription because they can be made thinner and lighter than conventional lenses.
What is component selection of auto transformer starter?
An Auto transformer motor starter is a device intended to start AC asynchronous motors, instead of connecting the electric motor directly to the electrical grid, it will connect it to the grid in more than just one step. Hence, it will behave as an electro mechanical soft starter. Although it is the "older" method of starting motors, it is still widely used due to its simplicity. The list of parts needed to "make" an "Auto Transformer Motor Starter" is composed from: 1. Auto transformer itself 2. 3 contactor (electrically sized to fit the motor) 3. Two timers, defining when the contactors will "close".
What is the application of pluse transformer?
why should we use pulse transformer rather than ordinary transformer
How the electric steering work and what is the advantage of electric steering system than the conventional steering?
Electric (Power) Steering works from a hydraulic pumping system, advantages are lighter steering for easier control.
What is conventional iconography?
Conventional Iconography is commonly characterized by being much more conventional than unconventional iconography.
Why autotransformer can handle more power than conventional transformer?
Perhaps you're referring to the size of the core? Strictly speaking, a 30MVA autotransformer can handle the same amount of power as a conventional transformer. But an autotransformer will be smaller than an equivalent conventional transformer. The reason is an autotransformer essentially has one winding on a core, with one tap including the whole winding, and another tap including only part of the winding. In a conventional transformer, power is transferred from one winding to the other by induction. In an auto, some is by conduction, and some is by induction. Here's an example comparison: Say we have a 10MVA 100kV/50kV 3 winding auto transformer. There are two parts of the winding - the series winding (the section of winding between the 100kV connection and 50kV connection), and the common winding (the section of winding between the 50kV connection to the neutral). If powered at 10MVA (full load), there will be: 10M / (100k * sqrt(3)) = 57.7 Amps flowing into the primary, and 10M / (50k * sqrt(3)) = 115.5 amps flowing out of the secondary So, 57.7A flow into the primary, down through the series winding and out the secondary. At the same time 57.7A flow up from the neutral through the common winding and out the secondary, resulting in a total secondary current of (57.7 + 57.7) = 115.5 (sorry, rounding is making my math look wrong!). Thus, the series winding is handling a total of: (100k - 50k)* 57.7A*sqrt(3) = 5MVA, and the common winding is handling a total of: (50k - 0) *57.7A*sqrt(3) = 5MVA So the series and common windings only have to be made to handle 1/2 the total load(for this example - it is 1/2 because the primary / secondary voltage is 2/1). In a conventional transformer, each winding carries the full load (10MVA), because it operates on induction (no conduction). If the votlage ratio between primary and secondary is too high, there is no real net savings in size (and thus cost), so a conventional transformer is often used. The cutoff point is around 4.
