A transformer is a
device that converts electrical energy from one circuit to another, or several
circuits. A changing current in any transformer coil causes a changing magnetic
flux in the core, which causes a changing electromotive force across all other
coils coiled around the same core. Without the need for a metallic link between
the two circuits, electrical energy can always be exchanged between them.
Depending on its
end-use, construction, supply, and function, electrical transformers can be
divided into several types. Based on the design, there are two types of
transformers: core type transformers and shell-type transformers. On the basis
of supply, there are two types of transformers: single-phase transformer and
three-phase transformer.
On the basis of
purpose, there are two types of transformers: step up transformer and step-down
transformer. Whereas on the basis of use, there are three types of
transformers: power transformer, distribution transformer and instrument
transformer. On the basis of cooling, there are three types of transformers:
self-cooled oil-filled transformers, water-cooled oil-filled transformers and
air-cooled (air blast) transformers.
Transformers are
used in electric power transmission to allow high-voltage transmission, which
lowers the loss caused by wire heating. This makes it possible to put producing
units at a cost-effective distance from electricity users. By the time it
reaches the customer, almost all of the world's electrical power has travelled
through a succession of transformers. A transformer is used in many electronic
equipments to convert voltage from distribution cable to useful values for
circuit requirements, usually immediately at the power line frequency or via a
switch mode power supply.

FAQs Related to Transformers
A transformer is
an electric gadget that transfers AC voltage from one level to another with the
least amount of energy loss possible. It is based on the electromagnetic
induction concept. A typical power transformer is made up of two coil sets:
primary and secondary. The number of turns on the main and secondary coils is
related to the rate of voltage transformation.
Transformers can
be operated at voltages lower than the nameplate rated voltage in some
instances. A transformer should never be run over its nameplate rating unless a
tap changer is available. When the voltage is lower than the rated voltage, the
KVA capacity is lowered accordingly.
The continual
expansion and contraction of the steel core inside the transformer causes
transformer hum or transformer noise. The quantity of flux determines core
expansion, which is determined by the applied voltage and the number of turns
in the transformer coils. The magnetic flux travelling through the transformer
core is constantly changing, causing the core to grow and shrink.
A power
transformer is mainly used in power transmission and distribution to either
step up or down a voltage level. In a circuit, an instrument transformer is
used to monitor voltage or current. Instrument transformers include current and
potential transformers, for instance.
The difference
between input and output power can be characterised as 'loss' in any electrical
equipment. Since an electrical transformer is a static device, it has no
mechanical losses (such as windage or friction losses). Simply electrical
losses make up a transformer (iron losses and copper losses). Transformer
losses are comparable to DC machine losses, with the exception that
transformers have no mechanical losses.
