While choosing a small auto
transformer can be relatively easy, since you just have to look at the kVA
rating, you might have to evaluate in detail when it comes to choosing
transformers for factories and mills. You have to judge the usability of a
transformer on two basic facets – firstly, the amount of load it can handle and
secondly, its application. If you are not a technical guy, you can contact Transformers manufacturers in India and
summon an engineer/technician for inspection to your factory. The technician
can check the power consumed by your machines before suggesting you a
transformer that can work well in your factory.
Following are the two main considerations while choosing a
transformer:
Ability to
handle load: It is considered a rule of thumb to choose a transformer in
such a manner that the load it is designated to handle is not more than 90% of
its capacity. For example, if you have to handle a load of 900kVA, it is
preferable to get a 1000kVA transformer installed. This way, it can succinctly
work even when there’s an overloading.
Application:
Different industries need a transformer for different purposes. While some want
a constant supply of voltage, there are others that might require a transformer
that can handle frequent overloading.
Also, one should take care of Unitized substation . They help a lot in handling load.
