Title: The Benefits of Transformers Oil Filtration

Welcome To Royal Transformers
The Benefits of Transformers Oil Filtration
A transformer is a machine that forms an
important part of the electric power supply
system in industrial settings and non-industrial
settings. Transformers are a constant part of
everyday life and need to be maintained to be
able to continuously function. An important part
of this maintenance is the purifying the
Transformer oil purification. Some companies may
hire Transformers oil filtration to do this for
What are the functions of the transformer oil?
  • To understand why it is important to purify the
    transformer oil, it is necessary to first
    understand the purpose of the transformer oil.
    Transformer oil has two primary functions
  • To act as an insulating layer in the transformer
  • To act as a coolant for the transformer
  • For these reasons, the transformer oil must be
    stable at high temperatures as well as have high
    chemical and electrical stability. Typically, an
    oil chosen to be used as a transformer oil must
    have a flashpoint of 140? or greater with a pour
    point of -30? or less and a breakdown voltage of
    30kV or more. This oil is commonly used in
    combination with a paper insulation inside a

What are the benefits of transformer oil
The purpose of filtering and purifying the
transformer oil is to remove the dirt, gases,
moisture, and other impurities that the oil
accumulates over time, even if it is not
currently in use. Therefore, the benefits of
purifying the oil are many
  • The filtration of the Furnace transformers India
    increases the insulating property of the
    transformer oil. The insulating property tends to
    reduce as the amount of dirt and sludge
    accumulated in the oil increases. With the aid of
    a filtering device, all minute particles are
    removed from the oil to restore its properties.
  • Purification of the oil restores its breakdown
  • The long life of the transformer depends on the
    ability of the transformer to insulate and cool
    the transformer. The purification of the oil
    increases these properties of the oil and
    therefore, increases the life of the transformer.

How can the properties of the oil be preserved?
These properties can be preserved by monitoring
them regularly. To monitor the quality of the
transformer oil, certain properties like
breakdown voltage and water content are measured.
Certain companies may choose to do these test
themselves but others may hire mobile transformer
oil filtration services who can test the oil for
these properties and also filter the oil in-situ.
The transformer oil filtration services hired
by a client may carry an on-line filtration
machine that has quite a few benefits. For
example, it is eco-friendly as there are no decay
products produced, it is easy to recharge and
transport, and so on. Moreover, there is no
downtime with an on-line transformer oil
filtration device and there is no spillage of the
oil that occurs during the handling of the oil.
These machines are commonly used in certain
industries like paper mills, refineries, steel
mines, coal mines, chemical plants, railways, and
so on.
What happens when the oil is NOT purified?
  • If the oil in the transformer is not purified
    regularly, then the following destructive
    processes occur in the transformer that reduces
    its overall lifespan
  • Arcing - an electric arc is formed in the oil
    that disrupts the breakdown voltage.
  • Overheating - the oil and the transformer
    overheats and malfunctions.
  • Corona Discharge - the oil particles are ionized
    through the discharge of an electric voltage in
  • Therefore, regular testing and filtration of the
    Distribution transformers India are of utmost
    importance if a transformer is to be guaranteed
    to have a cost-effective and long working life in
    any industry.
