are often placed in hostile situations. Extreme environments include a
wide range of temperatures, sometimes occurring in a period of 24 hours,
and can indicate the time sucked. Many manufacturers of transformers,
the stores offer full-service machine, create a complete distribution
transformer. Distribution transformers are designed for three types of
facilities - on pole mounted, built on the ground and sub-station. Pole
and back are usually the last point of a power distribution in general.
Although there are many small pieces of a Power transformer, it is divided into three main parts. The coils, the magnetic core and the tank.
Rolls, usually made of copper or aluminum wrap it around a magnet,
which is also known as snail. The regulation allows the current input to
a magnetic flux and in turn generates a magnetic field. The magnetic
core allows the transfer of the magnetic induction process. The coils
and core are known as active parts in the 3 phase transformer, as the work of the voltage regulation. The reservoir is used there as a protective container and oil cooling.
Distribution transformers can be divided into several categories. The
categories indicate the type of insulation used (immersed in a liquid or
dry), use the number of phases (single or triple), types of stress for
the insulation dry (low, medium) and BIL (impulse insulation base). BIL
is a term for the semi-volt dry type distribution transformers
that are prone to different levels of isolation. Liquid immersed
transformers are usually built with the same or similar level of BIL.
Distribution transformers generally do not produce small batches of heat, and will be built as a dry type transformer
. This means that only the air that is to isolate because they are less
flammable. more processors are hotter and therefore more flammable.
These require an insulating oil, mineral oil, which generally cool to
