Making a buying decision for a power transformer can be
complicated. You may trust the statements of the dealer or take your informed
stand. However, to consciously select the ideal configuration, you need to have
some basic knowledge of transformer concepts. This helps you make the best
bargain from an electrical transformer manufacturer of your choice.
This post highlights the major key factors that matter when
selecting the best power transformer.
1) Number of Phases
Single or Three-phase: the type of transformer you need
would be verbalized by the equipment type for which it is supposed. Usually,
single-phase
transformers are used for small-sized equipment utilized in households.
Three-Phase provides to large industries where the load is higher. The
power transformer
manufacturer mentions the phase and type of equipment with which the
transformer is compatible with its brochure.
2) Voltage Consideration
The primary and secondary voltages of the transformer
transmit to the input and output voltage requests for your equipment. Incoming
power supply defines these voltages.
3) Transformer Frequency
Power supply to your facility needs to be factored in for
considering the transformer’s frequency. Received and output frequencies may
vary in some occurrences. A frequency converter can be accepted alongside the
transformer to alter the output. Usually, imported equipment has varying
frequency requirements compared to local products.
4) kVA Rating of
The Transformer
Your purchasing decision must be influenced by the maximum
load you guess the transformer to be compatible with. kVA (kilo Volt-Ampere)
rating of the transformer is a sign of the size and nature of electrical load
the transformer is adept at a stable. If you are eager to custom transformer
manufacturing to suit the power needs of your equipment, you can state the kVA
rating to the manufacturer.
Accordingly, the voltage on the primary and secondary
windings as well as current capacity may be modified by the electrical
transformer manufacturer. Always keep in view the maximum load that is required
to be handled by the transformer.
5) Objective of Transformer
Another key factor that must be kept in mind is the purpose
of the transformer. Transformers can be used for a variety of causes. Your
choice should be based on the outcome i.e. whether it is to be installed for
isolation, for completing the K factor or to serve as an autotransformer.
6) Setting of the
Space where Transformer is to be installed.
Power transformer’s terms would vary based on the atmosphere
where you import to use it. If your transformer is to be used in an open space
uncovered to the weather elements, you need to edict oil-cooled or fluid-filled
ones. This would save the metal windings from the dangerous impact of weather.
The Tradition transformer manufacturing process also takes
into account the ambient temperature. The temperature of the space where a
transformer would function would be factored in during the design process.
If the transformer is meant to be used in hazardous space,
its specifications should fulfill the stipulations laid down by regulating
governmental authority.
7) Space
Considerations
Usually, power transformers are manufactured as per
pre-defined main sizes. However, it is not a restriction if you are running
short of installation space. You can specify your requirements to the
electrical transformer manufacturer to get it designed for installation in
space available with you. This simplifies safe and easy lifting and gathering
of transformer components.
8) Other Factors to
keep in Mind
You need to factor in the way the transformer is to be
designed. Hence, the
power
transformer manufacturer would design the wiring. This would also ensure
easy connections with other transformers in delta, star and other
interconnections. Preservation methods, i.e. vacuum cooling, oil cooling, and
other ways should also be considered. Choose sensibly, and you would reap the
highest return on investment.
