Transformer Oil Filtration Machines – THE NEED:
Did you know that dissolved gasses present in transformer oil can result in arcing, corona discharges and overheating that will ultimately reduce the electrical efficiency and lifetime of the transformer? Not only this but, the insulation strength of the oil is also adversely affected by the water contamination that sometimes goes down to about 30 ppm (parts per million). This calls for a dire need to adopt Transformer Oil Filtration Machine well in time!
A transformer oil filtering can potentially shorten the duration by which you would require the oil to be treated during the installation and maintenance of the Transformer.
Let’s take a look at some of the functions, benefits, parts, types, design, installation process, quality checking, delivery packages, and other FAQS about the YELOCO Transformer Oil Filtration Machine.

Chapter 1: What is a Transformer Oil Filtration machine?
Do you know what a Transformer Oil Purification machine looks like? Well, it contains lots of smaller machinery components combined to make one big oil purifying solution. Here’s what it would typically look like:

You must be wondering how these oil purification work. Well, here’s a summary of the process:
YELOCO Transformer Oil Purification machine initially filters out the water, gas, impurities and acetylene, hydrogen, methane, etc. and other dangerous components in the synthetic oil in an attempt to improve the synthetic performance of the oil. This step effectively ensures the normal operation of the electrical equipment to minimize the occurrences of incidents.
While conducting the vacuum extraction, the oil purifier machine can also fulfill the installation or on-site inspection of the transformer. To further shorten the oil treatment cycle, the machine can also complete the operation of water separation and gas separation in the transformer oil.
Where is the machine typically used?
It is widely used in power generation plants, substations, power utility plants, metallurgical fields, railroad sectors, and other industries that require on-site transformer inspection in a large scale transformer power station which uses 110 kV or more, and the rapid treatment of synthetic oil such as new oil and imported oil. It is an equipment that is required on priority in areas where sea level is 500 m or above.
Chapter 2: Benefits of a Transformer Oil Filtering machine

Chapter 5: Transformer Oil Filter machine Installation process
Follow our simple installation guide with a reference video, you’ll be just as good as a professional:
-
Place the equipment on the horizontal ground smoothly.
-
Connect the inlet and the outlet of the oil pipe and testing pipe properly.
-
Next, connect all power cables.
-
Turn the “Manual/ Automatic” knob switch to the “Automatic” setting and press the “Start” button switch. Under the control of the programmable logic controller PLC, the machine will work automatically.
-
Press the “Stop” button directly, and the equipment will stop working orderly under the control of programmable logic controller PLC.
There you go. Wasn’t that simple? It’s as safe as it sounds too!
After every set of oil filtration machine prepares well, we will make operation vides for customer reference.
Chapter 6: Transformer Oil Filtering machine use tips
These tips are used for all kinds of vacuum Transformer Oil Purifier machines. As a long-established brand in China, YELOCO, an oil filtration machine company, has had over 20 years of industrial credibility and integrity. The following tips will help you operate the vacuum Oil Purifier machine correctly and increase the life of not only the Transformer but also the oil.
-
Oil can only be circulated inside the transformer at 1,500 l/per hour. You can open ¾ of the oil outlet valve as well as the machine circulation valve to control oil flow capacity when you are filling oil into the Transformer.
-
Transfer of oil from one tank to another tank can be done at more than 1,500 L/per hour.
-
Oil should be circulated through machine filters more than once (twice is preferred) for better cleaning.
-
Oil should not be heated above 60 degrees Celsius. The maximum suggested temperature is 65 degrees.
-
If the oil going into the vacuum chamber is too hot, it will boil and overflow. Therefore, YELOCO sets the machine heating temperature to 60 degrees Celsius.
-
Oil going into the machine should be restricted at the source so that it prevents the machine from over-filling. This would mean that the machine vacuum chamber volume must match machine flow capacity. YELOCO Oil Purifier Machine’s design and make it according to these scientific ratios.
-
Dirty oil will need to be circulated slower so that the machine can withdraw moisture and prevent machine overflowing.
Chapter 7: How to package the Transformer Oil Filtration?
![Transformer oil filtration]()
Why are tin cases used? Well take a look at the following advantages:
-
Iron box packaging acts as an excellent barrier and provides comprehensive protective properties to the machine. These packaging materials have extremely low (almost zero) permeability to gas, water, and water vapor, good fragrance retention, and are completely opaque and effective. The same properties also avoid the harmful effects of ultraviolet rays from permeating inside the package. Plastics and paper packages do not match these properties for transporting and carrying such huge machines. Therefore, iron box packaging can provide excellent protection for the contents and is conducive to maintaining the quality of the goods for a long time.
-
Iron box packaging has good mechanical properties and carries high strength. This type of packaging also has good ductility and high strength. They can be processed by stamping, rolling, stretching, welding, etc., and can be made into thin walls. Packaging containers that have high compressive strength and are not easily damaged and can also be combined with other materials to form composite packaging materials with excellent comprehensive performance.
-
The packaging is convenient and hygienic. Its containers and internal coatings can generally meet the requirements of hygiene and safety and can adapt to different climatic conditions. The waste from this packaging is better treated and can be recycled.
