Types of transformers
In general, transformers are used for two purposes: signal matching and power supplies.


Power Transformers
Power transformers are used to convert from one voltage to another, at significant power levels.


Step-up transformers
A "step-up transformer" allows a device that requires a high voltage power supply to operate from a lower voltage source. The transformer takes in the low voltage at a high current and puts out the high voltage at a low current.

Step-down transformers
A "step-down transformer" allows a device that requires a low voltage power supply to operate from a higher voltage. The transformer takes in the high voltage at a low current and puts out a low voltage at a high current.

Isolation transformers
An "isolation transformer" does not raise or lower a voltage; whatever voltage comes in is what goes out. An isolation transformer prevents current from flowing directly from one side to the other. This usually serves as a safety device to prevent electrocution.


Variable auto-transformers
A "variable auto-transformer" (variac) can act like a step-up transformer or step-down transformer. It has a big knob on top that allows you to dial in whatever output voltage you want.

Inverters
An "inverter" takes a DC power source and boosts it up to a higher voltage. The most common type of inverter takes power from an automobile and cranks out 110 VAC to run appliances and power tools. Inverters are also used to operate fluorescent lamps from battery power.
Technically, an inverter isn't a transformer; it contains a transformer (and lots of other stuff).



Signal Transformers
"Signal transformers" also take one thing in and transform it to another thing out. But in this case, the power levels are low, and the transformed thing carries some type of information signal.
In most cases, these transformers are thought of as impedance matching.

Answer 5

In general transformers are used to change the voltage level. So in general there are two types of transformers ones which increase the voltage level and decrease the current level & those which decrease the voltage level and increase the current level.

Answer 6

you should take your temperature readings from the windings because it truly is the element you're protecting with techniques from measuring the temperature. with the help of the years, the e.M.F of the windings will motive small moves interior ensuing in artwork hardening of the copper. this can gradually more advantageous reason more advantageous suited resistance paths and warm joints. also, the encircling environment can motive overheating. If the ambient temp is excessively extreme or no air drift passes over the transformer, this can likely help in overheating.

Answer 7

single phase transformers can be classified into core type and shell type, and 3 phase transformers can be classified according to the type of connection made namely star and delta,

Answer 8

Also "toroidal" transformers can be used in electronic equipment due to their compactness.
