Actually an isolation transformer may be physically the same as a Step up/Step Down transformer. The main difference is in the way they are used.
Another difference is that in a normal transformer there will be capacitance between the 2 windings, between the windings and core, between the core and shell, etc. These capacitances bring in high frequency noise from outside, which will be transmitted in the secondary circuit. So [in an isolation transformer] wires are connected between each component, (not direct contact, but with insulation present). This permits a leakage current and eliminates unnecessary capacitance. I could make a start to answer this question. Isolation transformer: is a transformer with two separate windings, the primary and the secondary. There is an electrical isolation between the primary and the secondary. Nearly any type of transformer with two non-connected windings could be considered an "isolation" transformer, in that it electrically isolates the primary voltage from the secondary voltage. There are also Transformers with one winding (called auto-transformers) and connections for input and output. If the input is low voltage and the output a higher, then you can say it is a STEP-UP transformer. If the input is high and the output is low, then you can say it is a STEP-DOWN. This type of transformer can not by used where safety is a large factor.

∙ 11y agoA step-down transformer produces a secondary voltage that is lower than its primary voltage, while a step-up transformer produces a secondary voltage that is higher than its primary voltage. The primary voltage is the voltage applied to the transformer, whereas the secondary voltage is the voltage supplied by the transformer. It's the transformer's turns ratio that determines whether it is a step down or step up transformer: i.e. the ratio between the primary and secondary windings. If there are less turns on the secondary winding, then it's a step down transformer; if there are more turns on the secondary winding, then it's a step-up transformer.

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 is transformers job?
It depends on the type of transformer:transmission/distribution transformers step up or step down system voltagesisolation transformers electrically isolate two systems without affecting their voltagesmatching transformers are used in electronic circuits for impedance matchinginstrument transformers step down voltages (voltage transformers) or currents (current transformers) for measurement or protection applications
What are transformers designed to operate with?
to step up voltage or to step down voltage
What is the name given to the large transformers used in transmission systems to step up and step down?
step up transformer
Which conditions are used in step up transformer?
Transformers, step up or step down, use mutual induction in their operation.
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 the different between voltage generators and voltage transformers?
Generators generate and transformers step up or step down the voltage
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 are the two type of transfomer?
Step up transformers, and step down transformers
Is there a physically different shape between a step up transformer and a step down transformer?
There is no essential difference in the shape of those transformers. Whether it is a step up or a step down transformer only depends on which side the supply is connected to. The high-voltage side of the transformer has more turns of wire in the coil. High-power transformers have oil cooling and sometimes cooling fins on them, and there is no difference between step-up and step-down transformers.
Distribution transformer vs power transformer?
Power transformers are step-up or step-down transformers used in the electricity transmission system, whereas distribution transformers are step-down transformers used in the electricity distribution system.
What is difference betweena step up transformer and step down transformer?

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.
