A
transformer is an electrical device which transmits electrical power from one
circuit to another with added advantage of control over voltage and current.
Theoretically, power remaining constant voltage can be stepped-up or
stepped-down to suit a variety of applications. The basic principle in every
transformer still remains the same, that of electromagnetic induction.
Different technologies have evolved to manufacture different types of
transformers using the same concept.
Transformers
are used for commercial as well as industrial purposes. A number of factors
govern the type of the transformer to be used and electrical power transformer manufacturers provide an array of
solutions.
Some of the fundamental issues which drive the choice of
transformers can be listed as:
1 Voltage –
Higher voltage is used in transmission cables and industrial purposes while
lower voltage is required by commercial or household purposes. Power
transformers are used to step-up the volt to values exceeding 33kV while
Distribution transformers are used to step-down higher voltages to household
values (220V – 440V). Also transformers can be poly-phase or single depending
on the use.
Efficiency
– Power transformers become the option when efficiency has to be near 100%
during peak load while Distribution transformers are designed to work at 60-70%
output all day long. Other types of transformers also have lower efficiencies.
Type of
Core – Almost all the transformers use magnetic induction to vary the
voltage. But newer technologies have evolved and electronic transformers are
also used today. But they are suited for very low voltages and are limited to
electronic appliances. These type of transformers take less space but are not
durable as compared to magnetic ones.
Purpose –
The type of transformer to be used primarily depends on its application.
Some appliances need varying voltage while some may need rectangular voltage
pulse. The former requires an autotransformer while the later require a pulse
transformer. Indian Railways use a 33kV line to drive electric engines hence
power transformers are used.
