Introduction :

In this extremely fluid sector of electrical power transmission and distribution, transformers are of significant importance, as they cannot function properly without adequate cooling.

Transformer oil keeps transformers working effectively by serving as an insulator and heat dissipator for them.

The transformer oil is known to degrade as it ages during its life of service as a result of oxidative ageing and moisture pick-up, or through contamination and physical solids such as dirt and metal particles. This degradation may lead to deterioration of insulation strength and an increase in electrical conductivity to the point that transformers fail.

The Transformer Oil Filtration Machine can eliminate water content in the oil to 5% – 0.01 in 10–30 minutes (depending on operational conditions).

The system is designed to be staged in layers of filtration, whereby the level of dirt load can be controlled as per NAS 5 (ISO 15/12).

The product above is GreenPro certified. GreenPro is a Type-1 Ecolabel, and this is recognised by the Global Ecolabelling Network.

What is the Transformer Oil Filtration Plant?


The process of filtering out the transformer oil is a method that is used to purify the transformer oil that has been used to restore the insulation performance and enhance the service life of the transformer. It checks the status and health of the transformers before they go into a bad condition, which causes it a lot of inconvenience, damage, and impact from its source of power, the company, in a very bad and serious way.


Why Do We Need Transformer Oil Filtration?


The transformer oil, however, is subject to several challenges with time:

Contamination:Transformer oil becomes polluted with contaminants such as moisture, dust, and dissolved gases. These contaminants deteriorate the dielectric strength of the oil, causing it to fail as a coolant.

Decreased Cooling Effectiveness:In addition, contaminants impede the oil’s ability to transfer heat, causing operating temperatures to rise and transformers' windings and insulation to be at risk of damage.

Premature ageing:ageing of the oil is remarkably accelerated by contaminants in conjunction with high temperatures of service, shortening the overall service life of the oil by a significant margin, resulting in repeated change-outs.


The problems and the solutions that Transformer Oil Filtration Systems (TOFS) provide:


Contaminant Removal:TOFS uses different filtering methods to remove contaminants from the oil, thus recovering its dielectric strength and improving its quality.

Better cooling efficiency: TOFS allows the oil to flow freely and dissipate heat more effectively so that the risk of overheating is reduced as the service life of the transformer is extended.

Ageing Slower:reduced impurities and improved heat dissipation of the oil lessen the ageing of the oil. Slowing it lowers the cost of maintenance of your adapter.

Increased Safety:The preservative properties of TOFS help ensure stable oil, thereby protecting against electrical failure while subsequently reducing the likelihood of fire or explosion.

In summary, Transformer Oil Filtration Systems serve the important role of ensuring transformers remain healthy and live long lives despite the issues that arise from transformer oil degradation.


Characteristics of Transformer Oil Filtration:


Multi-Stage Filtration: A complex process that involves stages such as heating, degassing, dewatering, and fine filtration.

Portable Units:Individual flow-through units that are easily moved and set up in a particular area to provide filtering while limiting or eliminating downtime.

High Efficiency:Powerful to strip away water, gases, and particles to restore the oil's cleanness.

Easy to Operate:These are comprised of a user-friendly interface with easy control settings and an auto-on and off arrangement for easy operation.

● Solid Design:Strong and durable, it's sturdy and built to last, which is perfect for an application that doesn't move or open; otherwise, you will lose all the water.

Oil varieties that can be cleaned:

  • Transformer oil
  • Insulating oil

Applications across industries:

  • Mining, Refining, Forestry, Ports, Agriculture, and Quarries.
  • Power generation: coal, gas, hydro, nuclear, wind, solar.
  • Power utility plants
  • Power substations
  • Metallurgical fields
  • Railway Sector
  • CPP plants in the oil and gas industries
  • Steel Plants
  • Coal & metal mines
  • Chemical sector
  • Automobile manufacturing
  • Industries that require an on-site transformer

Advantages of Transformer Oil Filtration:

The moisture and impurities on the oil will be taken out by it.

  • It maintains the breakdown voltage of the transformer oil within the acceptable level.
  • It extends the life of the transformer oil and the transformer.
  • It can be used in the charged state of the transformer.
  • It can also be an insurance against unplanned shutdowns and enormous monetary losses to the transformer.

Key Consideration :


Quality of the oil: Regular checking of oil quality to know whether filtration is required.

Equipment:Checking the compatibility of the filtration system with the oil, as well as the transformer.

Capacity Adequacy:Choosing a system big enough to accommodate the amount of oil.

Downtime:Reducing downtime with units that are portable and efficient.

Maintenance:Keep the filtration system clean and maintained for the best performance.


Conclusion:


In summary, transformer oil filtration is an important maintenance process that can improve the operation, durability, and effectiveness of transformers.

Remove impurities and recondition the oil for normal operation of electrical systems in all types of industries. By investing in a dependable transformer oil purification system, you remove these risks and prevent expensive repairs, system failures, spills, etc.


FAQs:


A: That depends on the operating condition and how good the oil is.

A: Correct, there are onsite "portable filtration units" to get the job done and reduce downtime and trucking.

A: The filtering step removes moisture, gases, and particles from the oil and improves its dielectric strength and chemical stability.

A: Yes, it prolongs the life of transformers and lowers maintenance costs, so it is a good maintenance practice

A: Correct filtration helps to prevent oil leaks and environmental pollution and is therefore sustainable and compliant with rules.

A: Transformer oil filtration is a process that removes impurities from transformer oil to maintain the oil's quality and performance. The process involves:
  • Raising the oil temperature: The oil temperature is raised to 60°C.
  • Removing sludge and dirt: Sludge and dirt are removed from the oil.
  • Dehydration and degasification: The oil is dehydrated and degasified.

Our Oil Filtration Machines are exclusively designed to remove all types of contamination (moisture, dirt, gases, and varnish) from the oil.
Such contaminants can undermine the insulating qualities of the oil, lower transformer performance, increase susceptibility to faults, and in some cases result in premature ageing or failure.
