What is the difference between transformers and autotransformers?
Wiki User
∙ 13y ago
A transformer or, more-properly, a mutual transformer, has two windings, the primary and the secondary, which are electrically-isolated from each other, with the secondary voltage induced through mutual induction. An autotransformerconsists of one tapped winding, so the secondary circuit is not electrically isolated from the primary circuit. An autotransformer may be used to either increase or decrease the primary voltage, depending how it is connected.

∙ 13y agoTransformer's principle is Mutual induction
but Auto-Transformer's principle is Self induction.
Transformer has two winding but
auto-transformer has single winding
then auto transformer ratio is 2:1
but transformer ratio is 10:1 or 8:1

What are the functions of current transformers and the difference between current transformers and voltage transformers?
To sense the current flow across the current transformers and to monitor the current ratings. In current transformers no voltage variations occurs. but in voltage transformers it is mainly used to increase or decrease the voltage value.
What is the difference between Class TPS and Type X Current Transformers?
I am aware that Class TPS current transformers have a Low Leakage Flux design
What is zero voltage regulation in transformers and what it means?
'Zero voltage regulation' indicates that there is no difference between its 'no-load voltage' and its 'full-load voltage' -this is only the case for an 'ideal' transformer.
What the different between voltage generators and voltage transformers?
Generators generate and transformers step up or step down the voltage
What is the difference between primary electrical distribution and secondary distribution?
Primary electrical distribution carries medium voltage power to distribution transformers near the customers. Secondary electrical distribution transfers the power from the transformer to the households.
What is application area of autotransformers?
teslacoilcar ignition coilCRT television set flyback coilother transformers intended to produce extremely high voltages at low costvariacetc.

In transformers what's the difference between scavenger and demolisher?
well i think they appear the same form
Why autotransformers are not safe for supplying low voltage from a high voltage source?
Autotransformers are absolutely safe when supplying a lower voltage load from a higher voltage source, and are used to do so. However, they do not provide isolation. If isolation is considered essential, then autotransformers are not appropriate.
What is the difference between 208voltc and 240volts?
32 volts of course. But the real difference is the way the power company has "tapped" their supply step down transformers.
What are the types of transformer?
There are a variety of types of transformers. These include autotransformers, polyphase transformers, leakage transformer, resonant transformers, as well as audio transformers.the decepticons are the bad guys, and the autobots are the good guys. bumblebee and optimis prime are autobots. megatron is a decepticon.
What type transformer is best transformer?
The best type of transformer is the one that best fits your needs. There are power transformers, audio transformers, pulse transformers, autotransformers, RF transformers and many others. Transformers can have iron cores, nickel-iron or other alloy cores, ferrite cores, and air cores. They can be of laminated construction (the so-called E-I core), they can be toroidal, solenoidal etc. They can be smaller than a pea, and bigger than your house. What are you trying to build? Talk to some transformer manufacturers or look on their websites for the best transformer for your particular application. If you are trying to build an amplifier or power supply or similar, there are also some good special-interest forums that can offer suggestions.

What is the difference between a switch yard and a substation?
the switch yard consist of the buss, breakers and switches. where as when you add step up or step down transformers with or with out LTC'S (load tap changer).
What happens when unequal voltage ratios of transformers used in parallel operation of transformers?
You cannot connect transformers of different voltage in parallel. This is because circulating currents will be set up between the two transformers that may exceed their rated currents.
