Basic categorization of transformers can be done based upon their basic function. That is if a transformer is used to step down the voltage and called a step down transformer and to step up the voltage and called a step up transformer. At power generation house generally, step up ht or high tension transformers are used to transmit voltage & power from generating end to distribution end. This is required to reduce the line losses during power and voltage transmission up to consumer end. The generators used at power house are designed to generate ht or high tension voltage so that the same voltage can be fed to ht or high tension generator transformer for further step up to up to 66kV or 100kV or more.
Factors controlling and affecting the design of a transformer: Principle of operation of
a transformer. A transformer is a static machine which works on the principle of
mutual induction. HT/LT Distribution Transformer Design Software Solution. When
a coil is placed in the vicinity of an other coil, an emf if generated in the
coil with the change in rate of magnetic flux associated around the other coil.

of operation of a transformer. HT/LT Furnace Transformer Design
Software Solution with electrical data sheets. The magnetizing core is a very
essential part of a transformer. To get the preliminary dimensions
of transformer core we first need to know the specifications of
a transformer like - type of transformer (a
number of transformer types are mentioned above), rating of transformer in KVA,
number of phases of transformer, rated voltage for primary winding
of transformer and secondary winding of transformer, the operating frequency of transformer,
the vector group of transformer, short circuit impedance of transformer, no load
losses of transformer, load losses of transformer, tapping requirements
for transformer. HT/LT Power & Distribution Transformer Design Software with
Tank Design, Radiator Calculations, Conservator Tank Design, Oil calculation,
isolation transformers, earthing transformers, rectifier transformers.
Transformer design consultants and HT transformer manufacturers are using our
transformer design software packages.
The dimensions of the core of transformer are closely connected with the
dimensions of other transformer parts like windings of transformer. The emf or electro motive force, per
turn volt of a transformer is one of the most important values defining not only the
dimensions of a transformer, but the number of transformer winding turns too.
This also influences the value of transformer short circuit impedance,
the transformer weight and transformer losses etc.,. The transformer design flux
density in a transformer leg depends upon the grade of CRGO core laminations
that would be used in the transformer manufacture. For transformer core grades
M2 to M6, the transformer design flux density is taken between 1.5 Tesla to 1.7
Tesla. One can use Transformer Design Software for calculation of
winding data, core lamination data, tank data, oil quantity calculation, weight
calculation of windings, core and tank.
A transformer is an electrical machine which works on the law of electro magnetic
induction. Transformers are used to step up and step down the
voltage. A HT Transformer has two main windings - HT winding and LT windings. HT
winding is connected with the high tension input supply and LT winding gives low
tension output for connecting with the load.. This type of HT Transformer is
called step down HT Transformer. HT Transformer Design Software can be used to
design Step down HT transformer. You just need to input a few parameters and you
get detailed design output for HT winding data, LT winding data, core lamination
chart and tank details. Softbitonline HT Transformer Design Software Tool is

Limb
diameter and hence the limb area is automatically calculated depending upon the
flux density set. Transformer Design Software is very useful tool for design
calculations of HT Transformers. Change the flux density to change the core diameter (limb
diameter) to suit your design requirements. Change in value of (K, for LV) and
hence the change in value of “volt per turn” also directly affects the value of
core diameter. HT Transformer Design Software for winding data
calculations.
Window Height depends
upon the “
Window Factor” (Kw) and “
Ratio Window Height/Width”.
Both these variables are stored under “Settings” tab, “Core” tab. If the
“Window Factor” text box is set equal to zero (0) then this value (window
factor) is taken automatically depending upon the kVA rating of the transformer
otherwise you can enter your own value. This Transformer Design Software is very user
friendly and can be used by any person having basic design knowledge of HT
Transformer Design. And whatever value you enter in this
text box that is taken as the value for “Window Factor” and used in the
calculations. Transformer Design Software is open platform design tool for HT Transformer
design. By default the value for “Window Factor” is set to zero (0) so the
window factor value is automatically taken by the software itself depending upon
the kVA rating of the transformer. Let us design a HT Transformer using Softbit
HT Transformer Design Software Tool.
Ratio Window Height/Width:To achieve a desired window height and window width this ration can be
changed.
LV Winding Type- You can choose and select the LV
winding type from combo list as per your design requirements. LV winding types
available are – foil*, spiral, helical and disc
TW Winding Type

HV
Winding TypeYou can
choose and select the HV winding type from list as per your design requirements.
HV winding types available are – crossover, disc and foil. You can design a HT
Transformer using round conductor, flat strip and/or foil. This helps you to
design and manufacture a HT Transformer as your requirements & specifications.
This all is possible with Softbit HT Transformer Design Software Tool.
We can get instant calculations for HT and LT windings, conductor size, number
of turns, weight of conductor, dimensions of coils, core details, sizes of core
laminations, weight of core laminations, tank design, tank dimensions, oil
quantity, oil weight. This way HT Transformer Design Software Tool is a necessity
of a HT Transformer Designer today.
HT Transformers are used for stepping down of voltage to required utility level,
used as Furnace Transformer, Isolation Transformer, Servo Transformer, Generator
Transformer, Solar power transformer for power transmission to remote locations,
wind application HT Transformer for voltage step up. We can use Softbitonline HT
Transformer Design Software Tool to design any type of HT Transformer.
You get instant output
reports and data sheets for review and sending to manufacturing departments for
review and taking action. HT Transformer Design Software is developed for HT
Single Phase and Three Phase Transformer Design. Designer can get the required
height of HT transformer by controlling the axial length of LT coil. Axial
length of LT coil can be controlled by adjusting the width of LT coil of HT
Transformer. Softbit has given a special option through a factor so that you can
get the desired width of LT strip and hence to control the height of the window
and transformer. The transformer would be designed by HT Transformer Design
Software at set or given impedance and losses.
Height of HT transformer is required to be set taking into consideration the
site, location of installation and transportation of transformer at site through
road. Generally EHT power transformers are big in size so its must to take into
consideration its dimensions keeping in mind its transportation to site,
installation location etc.,. The variation in dimensions does not impact the
functioning, impedance and load losses data. This is all adjusted automatically.
The HT Transformer Design Software varies the current density to achieve the
desired results. The change in current density changes the cross section area of
the conductor and hence the the dimensions of the conductor. We can control the
size (W * H) of LT strip by changing the factor. We can also control the
conductor losses or eddy current losses this way.
Edges of strips are generally chamfered a little bit for mechanical reasons.
Alert is given if the ratio of LT conductor width vs thickness is beyond a
specified set value
You can use the HT Transformer Design Software Tool for designing HT
distribution transformer, HT power transformers, EHT transformers for electrical
energy transmission at long distances, HT furnace transformers, HT Welding
transformers, HT Isolation Transformers, HT Generator Transformers, HT Wind mill
transformers for power transmission from wind generation turbine to consumer end.
Welding transformers are generally designed with low LT voltage and high current
so that high currents can flow through the secondary windings while shorting the
electrode with the earth point. You can use round conductor or rectangular strip
as per your choice or requirements. We need cooling of the windings of welding
transformers as very high currents flow in the windings. To cool the windings
we can use oil as cooling medium. In case the oil is restricted to be used then
forced air can be used to cool the windings of transformer. While we design a
transformer and its enclosure or tank, the quantity of oil is calculated
depending upon the size of the tank. The size of the tank can be changed by
modifying the gaps between outer windings and tank sides in all the four sides.

the complete processing taking into account the modified parameters and will
generate fresh design sheets..
With our ht or high tension or high voltage transformer design software you can adjust the height of the transformer and in turn its tank height to suit your space requirements. A factor is given that can be changed to adjust the height of transformer as per requirements. As you know the height of a transformer directly depends upon the window height of the core frame. And window height of the core frame depends upon the axial height of the LT/HT coils, top and bottom spacer gaps, end rings. The axial height of LT coil depends upon the width of LT strip. Now we control the width of the LT coil to control the over all size of transformer and finally its tank. Transformer Design Software is the best tool to achieve your desired results.
