The transformer you describe is being used as a step-down transformer, and is classified as an electrical machine. The transformer could either be a mutual transformer, consisting of two, electrically-isolated coils, or an auto-transformer which uses a common coil between its primary and secondary circuits.

What is ferro-resonance effects?
The effects of ferro-resonance are the ungrounded primary transformers, higher distribution in the voltage systems. Other effects are the lightly loaded transformers.
Which type of electrical power-related tranformer steps up the voltage to several hundred thousand volts in order to reduce energy losses?
Step-up transformers of the type you describe are three-phase transformers which, in the transmission system, are classified as 'power transformers'.
Why secondary windings of current transformers are shorted?
Current transformers (CTs) -together with voltage (or potential) transformers- are 'instrument transformers'. CTs are used to enable large currents flowing in high-voltage systems to be measured, while electrically-isolating the ammeter (termed a 'burden') from the h.v. system. They are also used to monitor h.v. currents for high-voltage protection systems. Before disconnecting its burden, the secondary of a CT must be short-circuited, and remain short-circuited until after the burden has been replaced. This is because a dangerously-high voltage will appear across the open terminals of any energised CT.
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 at least 2 types of electrical transformers in science?
A variety of electrical transformers are produced for a variety of purposes. All of the types use the same principle discovered by Michael Faraday, and employ many of the same parts. The various types include. Audio transformers, Instrument transformers, Pulse transformers, Power transformers, RF transformers. .
What are the uses of instrument?
The term, 'instrument transformer', is applied to current transformers and voltage transformers (known, in North America, as 'potential Transformers'). The primary windings of instrument transformers are connected to high-voltage systems, and their secondary windings provide outputs to measuring instruments or protective relays. They also provide isolation from the high-voltage system for the purpose of safety.
What is ferro-resonance effects?
The effects of ferro-resonance are the ungrounded primary transformers, higher distribution in the voltage systems. Other effects are the lightly loaded transformers.
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 are the two types of transformers?
The two general categories of transformer, based on their construction, are (a) mutual transformers and (b) autotransformers.Mutual transformers have two coils, or 'windings', termed the primary (input side) and the secondary (output side), which are electrically isolated from each other, being linked with a magnetic field.Autotransformers have a single, shared, winding and so, do not provide isolation between the primary and secondary sides.Mutual transformers can be further classified, according to their function: e.g. power transformers, distribution transformers, isolation transformers, instrument transformers, matching transformers, etc.
What are the advantages of power transformers over voltage transformers?
Power transformers can be used for power transformation. Voltage transformers are not suitable for high power applications.
Electrical Properties of Transformers why you use it?
Transformers are used to convert electricity from high voltage to low voltage and from low voltage to high voltage.
What the different between voltage generators and voltage transformers?
Generators generate and transformers step up or step down the voltage
What is The voltage that is provided by the transformers?
The secondary voltage.
What devices use transformers?
Transformers are used to change the voltage in a circuit from high to low or from low to high. Some of the gadgets that use transformers include surround sound systems, the CPU power supply and speakers which have inbuilt amplifiers.
