What does auto in autotransformer stands for?
"Auto" refers to the single winding used an auto transformer.
How do you convert 230v to 208 volts single phase?
A source of 208 volts can be obtained from any two legs of a three phase four wire 208 volt system. The two legs are classed as single phase 208 volts. The lead tags can be L1-L2, L2-L3, or L3-L1 all of which will give you 208 volts. Any of these lead tags to the grounded star point (wye) will give you 120 volts.
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
How single phase preventer working?
working of single phase preventor
What is the advantages and disadvantages of single phase and three phase?
Single phase inherently requires less equipment (it's cheaper). Three phase motors are more efficient than single phase.
What is a single phase variac?
It is a variable autotransformer, a transformer with a sliding contact on the winding connected to a control knob, that allows the output voltage to be varied.
What is an autotransformer?
An autotransformer is a transformer where the primary and secondary are a single winding.
How do you get phase shift in Hartley oscillator?
basicaly the two inductors work as an autotransformer,providing a phase shift of 180 degree
How do you install a 110v receptacle from a 3 phase breaker box if there are no neutrals in the breaker box?
If there is no neutral available you cannot, unless you use an autotransformer and derive a neutral. A panel with no neutral is called a power panel and is used to supply 240 single and three phase loads.

How many coils does a autotransformer have?
only single coil is use as a primary and secondary coil in a auto transformer.
Is the type of wiring in most homes single-phase or three-phase?
Single phase.
Two phase instruments?
There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
Advantages of autotransformer?
the power can flow either way through autotransformer (345/120 kV) ?
Is Europe ac power single phase?
In Europe they have both single phase and three phase.
