Why Filter with Our TFS MG range of Insulating Fluid Treatment Systems?

Insulating Fluid is vitally important for the safe and efficient operation of many types of electrical equipment. In addition to its insulating properties, the fluid is used as a coolant in transformers and as a means of arc suppression in circuit breakers. In each case the operation of the electrical equipment depends on the purity of the insulating fluid, which in services can be contaminated by particles, water, gases and chemical products.

Should electrical equipment be continuously operated with contaminated fluid, its efficiency will be impaired, resulting eventually in the risk of total failure. Typically insulating fluid is contaminated in the following ways:

  • Particles including fibres, rust and colloidal carbon.
  • Free and dissolved water.
  • Gases produced by fluid ageing, equipment failure and arc suppression in switchgear.
  • Chemical products caused by oxidation, as well as cross contamination by other products.

Although individually each contaminant reduces the insulating characteristics of the fluid by around 20%, the combination of fibres from insulating material and water can reduce its performance by up to 90%.

Insulating fluid treatment maintains the integrity of the fluid and hence the efficient utilisation of the electrical equipment.

Contaminants in Insulating Oil

WATER

Enters During Transportation, Oil Temperature Change, Produced During Oxidation of Oil & Paper

 

FIBRES

During Transportation From Cleaning Cloths From Paper Insulation

 

CARBON

Produced During Arcing in Switchgear Produced During Tapchanger Operation

Major Particle Distribution Size, 0.5 – 15 Micron Requires Ultra Fine Filtration for Removal

 

GASES

Produced by Heat, Corona, Sparking, Arcing

Overheating: Ethylene

Corona: Hydrogen

Arcing: Acetylene

Used for Fault Analysis

 

RUST, OXIDE

During Transportation

Dirty Drums

From Steel Pipes

From Corrosion Inside Transformers

 

ACIDITY

Formed by Unstable Oil, Oxygen, Iron or Copper

Organic Acids Create Sludge

Promote Degradation of The Paper Insulation

Oxidation Forms More Water

 

SLUDGE

Produced in Oils Having a High Acidity Level

Organic Acids duce Sludge

Formed by Unstable Oil, Oxygen, Iron or Copper

Deposited in Layers within The Transformer

 

 

Our Transformer oil treatment plants provide a tried and tested solution for the dehydration and treatment of a range of insulating oil. In many cases, treatment with a plant from our MG range of plants will result in an oil of a higher specification than when originally supplied as new.

TFS  Australian made Transformer oil treatment plants are used around the world by major electrical utilities, end users, service companies and transformer builders.

Our plants offer high performance, reliability and ease of use. Treatment with our plants will;

  • Reduce total water content from 50ppm to less than 5ppm in a single pass, and to less than 3ppm in three passes.
  • Remove virtually all suspended solids greater than 1 micron.
  • Reduce dissolved gas content from 10% by volume to less than 0.25% by volume in a single pass, and to less than 0.1% by volume in three passes.

TFS MG Range of transformer oil treatment plants are available using our disposable high efficiency microglass filter cartridges,.

Transformer Filtration Systems have the experience and expertise to provide tailor made solutions specifically designed to suit your business needs.

Dimensions and Weights are estimated, dimensions & weights will vary when optional extras are added and should be used as a guide only.

 

Plants are available in a range of sizes and configurations, with treatment capacities from 3000 to 6000 litre/hour treatment capacity, as either fixed, semi‑mobile or fully mobile, towable plants. Both Plants can be run at much slower speeds and on half heat reducing power requirements.

Our UK VOKES factory trained team can configure your plant to suit your specific applications.
