Understanding and Selecting the Best Single
Phase Transformer Miracle Electronics
Transformers are those electrical devices that
convert higher voltages into lower voltages to
make it ideal for household usage. They transfer
electrical energy between circuits without
modifying the frequency. With a wide variety of
transformers available, each one differs in
terms of their design. However, each transformer
follows the basic principle of Faradays Law
that was invented in 1831 by an English physicist
named Michael Faraday. This law explains how
most electrical motors, generators, inductors,
and transformers work by relating the electric
circuit and magnetic field.
Faraday's First Law Any change in the magnetic
field of a coil of wire will induce an
electromotive force in the coil. If the conductor
circuit is closed, the current will circulate
through the circuit. Faraday's Second Law The
magnitude of electromotive forces induced in the
coil is equal to the rate of change of flux that
links with the coil, which is the product of the
number of turns in the coil and the flux
associated with the coil. What is a single
phase transformer? From a wide range of power
transformers in India, today in this blog we will
discuss about the single phase transformer,
which is a device that uses a single
phase AC current. These
2
transformers depend upon on a voltage cycle that
operates in an integrated time phase. They are
used to lower long distance electrical signals
into power levels that are utilized by
light commercial and residential applications.
Single phase transformers generally have
adjustable turn ratios, while certain
transformers have a fixed 11 ratio between
primary windings and secondary windings to
isolate circuits. The industrial regulations and
utility infrastructure decides upon the highest
voltage in single phase transformers. How do
single phase transformers work? Just like any
other transformer, even single phase transformers
comprise of primary and secondary windings that
feature insulated wires wound on a single iron
core. The primary winding is connected to an AC
source, while the secondary winding is connected
to the load. The iron core links the flux
between both these windings. On energizing, the
primary winding produces an electromagnetic
field that collapses in the iron core, which in
turn induces power at the load. Such magnetic
flux (collapse and power build up) occurs six
times a second in an AC circuit. By altering the
primary and secondary windings, the amount of
voltage and amperes between the load and source
can be altered. Remember that if the voltage is
increased by 2 times, the current in secondary
coil will reduce to ½ the value of current in the
primary coil. How to select the best single
phase transformer? While selecting a single phase
transformer for your application, you need to
consider a few significant factors like primary
and secondary voltage rating, power rating,
secondary current rating, operating frequency
range, and operating temperature. You may get in
touch with an electrical expert, or read the
manufacturer specification to make an informed
decision about the right type of single phase
transformer you require for your application.
And, if you know what you need to buy, you can
