Title: How To Build Three Phase Transformers - Miracle Electronics
1How To Build Three Phase Transformers - Miracle
Electronics Three-phase or 3-phase supplies are
used for electrical power generation,
transmission and distribution. They have many
advantages over single-phase supply and thus, are
highly used in industries. 3-phase transformers
have to deal with three alternating currents and
voltages. A transformer cannot change
single-phase to 3-phase or vice-versa. To make
the transformer connections compatible with
3-phase supplies, they need to be connected in a
particular pattern to form a 3-phase transformer
configuration. In a 3-phase transformer, three
primary windings of three single- phase
transformers are connected to one another and
three secondary windings are inter-connected in
a fixed configuration to get a 3-phase supply.
The sets of primary and secondary windings in thre
e phase transformers are connected in either ?
or Y configurations to form a
2complete unit. The winding options may be Y Y
or Y ? or ? Y or ? ?. The reason for
choosing a ? or Y configuration for transformer
winding connections is that ? connections enjoy a
higher level of reliability and Y connections
can provide chances for multiple voltages. (In a
? configuration, if one winding fails open, the
other two can still maintain full line voltages
to the load, thus higher reliability). 3-phase
transformers can also be built by mounting three
pairs of single-phase windings onto a single
laminated core. However, a single 3-phase
transformer is much better than three individual
single-phase transformers connected together
because the copper and iron cores are used more
effectively, resulting in a smaller, lighter and
much inexpensive transformer for the same kVA
rating. Whatever kind of transformer, it is very
essential that the connections made are perfect
because wrong connections will damage the
equipment and cause injuries too. You can rely on
Miracle Electronics to provide you with the
best-in-quality three phase transformers that
are efficient and fault-free. The high
performance transformers are built on high
quality benchmarks that are in accordance with
International standards, due to which they are
used across numerous industries across the globe
effectively, making Miracle Electronics the best
transformer manufacturer in India. Let us now
have a look at the several supply combinations
you can have for single-phase or 3-phase powers
when you connect transformers.
3- SINGLE-PHASE POWER single voltage This
includes one hot conductor and one grounded
conductor or two hot conductors, where both the
conductors can be connected for single voltage. - SINGLE-PHASE POWER dual voltage This include
two hot conductors and one grounded neutral
conductor, where two hot conductors are
connected for full voltage and one hot
conductor and the grounded neutral conductor are
connected for lower voltage. - 3-PHASE POWER single voltage This includes
three hot conductors that are connected for
3-phase voltage and any pair can be connected
for single-phase voltage. - 3-PHASE POWER dual voltage This includes three
hot conductors and a grounded neutral conductor,
where all three hot conductors are connected for
3-phase power and any two hot conductors are
connected with the grounded neutral conductor
for single-phase voltage. - For more information visit https//www.miracle.ne
