Transformer oil acts as a dielectric medium in oil-filled transformers to cool and insulate the transformer windings and core. Transformer windings and core, which are highly stable at high temperatures, are fully immersed in these oils as they prevent the contact of atmospheric oxygen with the cellulose paper insulation of windings, which are highly prone to oxidization. There are mainly three types of transformer oils: mineral-based, silicone-based, and bio-based. Of these, mineral-based transformer oil is largely preferred mainly because of its good electrical and cooling properties and cost-effectiveness.

Which kind of transformer oil to buy?

A great number of manufacturers and distributor of transformer oil operate in the international and national markets.

Transformer oils, a liquid for cooling and insulating power transformers and other high voltage gear, remain an indispensible part of power transmission and generation industry.

In scientific terms, transformer oil is a product of crude oil refining. The properties of transformer oil depend heavily on the quality and parameters of the raw material. Performance of the oil is defined by the positive and negative properties of the crude oil. Chemical composition of the oil is quite complex. It includes the following components: paraffin (10-15%), naphtenes or cycloparaffins (60-70%), aromatic hydrocarbons (15-20%), asphalt (1-2%), sulfuric compounds (<1%), nitric compounds (<0.8%), naphtenic acids (<0.02%) and antioxidation additive (0.5 – 0.5%).

Transformer oils must be highly resistant to oxidation, must not form sludge and emulsify in contact with water. Antioxidation additives are an important component present in virtually all types of transformer oil.

The efficiency of such additive is based on the ability to react with active peroxide radicals, which form in the result of hydrocarbon oxidation reaction and are its primary carriers.

Presence of additives in transformer oil slows aging of the oil. As soon as the additive is depleted, the oil ages in about the same amount of time as an oil without the additive.

The main properties of transformer oil are its viscosity and density. These have a pronounced effect on function of the oil. Higher viscosity may mean better dielectric strength, while also having a detrimental effect on cooling. Optimal kinetic viscosity of the oil at 20C is about 28-30×10-6 m2/second.

Dissipation factor, in turn, is responsible for the oil’s dielectric properties and protects the system from possible short circuits.

These and other properties of transformer oil are improved by the use of high quality crude oil, deep refining and introduction of additives which increase the oil’s oxidation stability and reduce corrosion.

When the oil is significantly oxidized under the influence of water, solids, air and other gases, high temperature etc, the oil should be replaced. If degradation of oil properties is not detected in time, transformers may fail. When the oil decays, it can no longer serve as a dielectric and starts to react with the metal of the transformer tank, hinders cooling and may lead to short circuits.

The following are some of the oils which may be purchase in the local market.

VG type oil is made from paraffinic crude oil by catalytic process with the adition of an antioxidation  additive. It is a good dielectric and is rather stable against oxidation. It is mostly used in higher voltage equipment.

GK type oil is made of sulfuric paraffinic oils by hydrocracking. It also contains ionol antioxidant, which ensures good stability and dielectric properties of the oil. It is another kind of oil used in higher voltage systems.

TKp oil is made from low-sulfur naphtenic crude by acid-alkali purification. The oil also contains the antioxidant. This oil is recommended for equipment with voltage up to 500 kV.

Oil selection depends not only on the type of electric equipment, but also and mostly on the individual requirements of the facility. Most of transformer oils are universal. In all cases, the correct selection of oil type with consideration of local climatic and physical operating conditions ensures reliable and stable operation of power equipment: high voltage transformers and switch gear.

Quality Assurance: Methods of transformer oil testing

Quality of transformer oil is tested in several stages of its use. Regular control of the oil’s quality is a part of the process of servicing electric equipment. The main parameters of oil and its purity indicate transformer condition.

The ability of the oil to maintain its original properties during operation of electric equipment is referred to as oil stability. If the equipment has not defects and operates without failures, the parameters of new oil change very slowly. New transformer oil has light color and complies with regulations, which define the oil’s dielectric strength and other properties. In use, stability of the oil decreases and notable changes occur, the color changes to dark.

Poor oil quality is indicated by high ash content, increased acidity and presence of low molecular acids. Acidic sludge forms in contaminated oil, which disrupts cellulose insulation and reacts with the metals of the transformer’s internal components.

Oil tests can identify the beginning of oil degradation.

The main physical and chemical properties tested are the oil’s dielectric strength, dissipation factor, flashpoint, color, solid, water and gas content as well as acid number.

Dielectric strength is one of the most important indications of oil stability and this is often the first test performed. It is calculated as an average of five breakthrough achieved in a standard discharger with two electrodes at 2.5 mm distance. Six breakthroughs are achieved in the test and the last five are averaged. If the oil is fresh, the lowest allowable breakthrough voltage is 30 kV. In some transformers, that is as good as needed.

Decreasing dielectric strength indicates contamination of the oil by gas, moisture, cellulose fibers or other particulate matter.

A similar process is used to calculate dissipation factor. The oil’s ability to neutralize energy, prevent breakthroughs and cool the transformer is characterized by the oil’s quality and purity, or acidity. In general, increased dissipation factor means degradation of the oil’s dielectric capabilities.

The color of transformer oil changes from light yellow to cloudy brown under the influence of temperature, contaminants and current. The color is not in itself an indication of any specific problem, but dark color is usually an indication of aged oil.

The presence of solid particles and the acid number of the oil are related. Unsolved materials accumulated in the oil in the form of sludge or suspended particles (fibers, dust, solved paint, metal particles, ash etc) degrade the oil’s dielectric properties and promote oil oxidation. The more particles are present in the oil, the faster the oil ages. The acid number is expressed as milligrams of KOH required to neutralize all acids in a gram of oil and indicates the degree of oil aging. Normal acid number is 0.25 mg KOH/g, while the limit of contaminant content is 515 ppm.

Moisture and gas content in transformer oil is tested thoroughly, because water and air are some of the main “catalysts” of oil aging process.

Moisture content is measured as amount of hydrogen when reacting the oil with calcium hydride in a certain time. Gas content is measured by an absorptiometric analyzer or a chromatographer.

Flashpoint and setting point are indications of general fire safety of the oil and its ability to operate in adverse temperature conditions.

Therefore, the advantages of testing and analyzing transformer oil before starting electric equipment and during regular maintenance, allow to determine the equipment’s efficiency, operation conditions and possibility of malfunctions. If the purity and quality regulations are followed, the facility is safe from failure and downtime of equipment and related repair costs.

Classification of transformer oil storage tanks

In power transformers and in electric equipment in general, oil is used for insulation of equipment and for cooling. Using certain types of oil for power systems is regulated by international and national legislation and standards. The purpose if to keep equipment and systems in good condition, which depends on some parameters and general condition of transformer oil.

Any business with uses oil is concerned with the issue of oil storage. This is especially important for the energy sector.

Transformer oil may come form the factory or substation in different condition: fresh from the manufacturer in possible increased water and gas content accumulated during transportation; oil purified after shipment and ready for operation; clean oil, filled into the equipment, compliant with specifications; used oil, removed from equipment after loss of functional properties; regeneratedused oil after physical, chemical or combined treatment with restoration of original specifications and ready for further use.

Transformer oil delivered from the manufacturer and purified as necessary to comply with the regulations, is stored in liquid storage tanks at oil facilities.

For the purposes of fire safety, the manufacturer must strictly adhere to the requirements of national standards. However, the actual method of storage, availability of specially equipped buildings, tanks and service equipment is variable.

A wide range of oil storage tanks is out in the market. There are soft tanks, which allow to drain and store oil quickly servicing and transformer downtime, but are more suited for reduction of automobile transportation of oil to interim storage facilities.

For actual storage of liquids, the most widely used are vertical cylindrical tanks, equipped with level and quality controls, agitation systems and temperature sensors and maintenance systems.

A vertical insulated tank is made of construction steel with heat carrier circulation pipes below the surface. For servicing, a ladder is mounted on the tank with protective rail along the top. Temperature is monitored by a thermistor installed in the bottom of the tank, which shows the temperature on the control panel. The heat exchange system is an array of pipes and insulation jackets.

Correct oil storage systems allow to keep the oil in good condition and preserve its specification, lowering the cost of additional purification and regeneration due to premature aging of the oil.

Expert opinion about the classes of the hydraulic oil purity

Reliable operation of hydraulic equipment, widely used in various industrial facilities, depends mostly on the quality of the internal cooling and lubrication oil. Such machines operate under heavy loads and sometimes in difficult conditions. Regular maintenance of industrial equipment allows to detect possible malfunction in a timely manner. Presence of solid particles in the oil quickly degrades the oil; among such particles 70-85% are quartz,  10 – 15% aluminum oxide and 5 – 10% iron oxide. Contamination of hydraulic oil disrupts operation of safety and regulation valves.

Complete replacement of oil is not a complete solution, since the system itself is contaminated by metals and sludge. These will contaminate fresh oil filled into the system. The new oil can also be contaminated during incorrect transportation, storage and handling.

The filters built into the hydraulic systems do not ensure the required purification of oil. Oil purity class is not an indication of its compatibility with certain industrial equipment type. Also, it cannot give a precise answer as to the oil’s reliable operation. Equipment loads are a direct influence on the rate of degradation of the oil.

For reliable operation of oil systems and prevention of malfunctions caused by irreversible processes in the oil, it is necessary to use hydraulic oil purification plants.

Selection criteria of such systems are low filtration and regeneration costs, reduction of repair and maintenance costs, high purity of processed oil, removal of sludge and contaminants from oil tanks, mobile or stationary design, compliance with fire and health regulations.

To comply with the above criteria, as well as for minimization of oil purification expenses, GlobeCore developed UVR type units for oil purification and regeneration. These plants are an efficient one-stop substitution for a whole array of filtration and service equipment. One UVR plant on a mobile platform can quickly service several machines. It can easily move around the facility and does not require readjustment for different kinds of oil or equipment.

Availability of oil purification and regeneration plants increases hydraulic system reliability and extends service life, reducing maintenance costs. The complete regeneration and filtration process keeps the oil in specs and reduces the amount of maintenance work and downtime.

The laws of hydraulic oil purification

The laws of hydraulic oil purification

Oils and other operating liquids, used as lubricants and coolants in various industrial equipment, are prone to degrade under the influence of elevated temperatures, pressures or flow. The functionality of oils depends on viscosity, oxidation stability and purity, lubrication capabilities, corrosion and emulsification. The difference of hydraulic oils from other oils is the relatively higher viscosity of the oil for high pressure hydraulic actuators. High viscosity makes operation of equipment unsafe or impossible. On the other hand, to ensure efficient operation of the systems, oil viscosity must exceed 20 cSt. Otherwise the pumps will experience increased wear, causing rapid loss of efficiency.

Transformer oil degassing as a part of comprehensive purification system

While operating expensive power equipment, such as compressors, turbines, hydraulic presses, heat exchangers and power transformers, unforeseen malfunctions will happen. In rare cases failures are caused by overvoltage of the grid or human mistake, since operation of power equipment is a safety issue. Equipment downtime, failures and malfunctions are most often caused by the problems of internal components or insulation. Oil of various kinds are used for servicing of different industrial machinery. As a result of contamination by solid particles or moisture and air, as well as high temperatures, equipment may fail which may stop the whole manufacturing process.

Comprehensive oil purification systems are becoming more used recently; if before industrial oil service life could be extended by separate degassing, drying and filtration systems, with totally spent oil being disposed of, now operation of comprehensive oil purification and regeneration systems becomes preferable.

Removing gas, water emulsions, and harmful oxidation products form the oil extends the service life of the expensive insulation material and ensures the power equipment is adequately protected.

Comparison of purification and regeneration plants made by different companies yields significant differences.

Most of the modern manufacturers emphasize removal of water in all forms and solid particles from turbine, compressor, hydraulic and industrial water. Removal of air, gas and volatile hydrocarbons is a secondary function.

Despite the normal production levels of such systems and their seeming versatility, there are other options with more worth.

The whole range of GlobeCore degassing, purification and regeneration of oil by GlobeCore is focused on all processes at the same time, in one pass and with reactivation of purifying media.

One full regeneration cycle of oil coming directly from power equipment allows to remove gas, water and particulate matter form the oil; it is also possible to use adsorption media to regenerate the oil entirely. GlobeCore’s sorbents offer additional savings due to the reactivation capability.

A complete GlobeCore plant for degassing, filtration and regeneration of oil and other liquids is an optimal choice of service equipment for control of production process and ruling out any unpleasant surprises.

Using of the turbine oil: benefits and testing

Oil used in various industries are divided into various types and subtypes. Physical properties and chemical composition divide oil into classes and categories. Various industries require specific oil types.

There is a group of oils for the energy industry, which includes turbine, dielectric (transformer) and compressor oils. Specific requirements are applied to each of the categories.

Also, depending on oil type, moisture and gas content are regulated, as well as some other specifications.

Since oils inevitably age with time under the influence of water and solid particle contamination, the natural process of oil consumption becomes a problem related to the costs of repairs and downtime, with the obvious adverse effect on company revenues.

In the case of turbine oil, sediment on the surface of internal parts may lead to serious problems, including wear of regulation devices, command valves etc. In turn, moisture promotes corrosion, dilutes anti-oxidation additives and increases foaming, which also degrades lubrication.

Therefore, power generation facilities implement systems for turbine oil quality control both during operation and storage. Neglecting the regulations may cause serious problems for turbines, including failures and extended downtime due to complete or partial breakdown of equipment.

Contamination of turbine oils leads to degradation of their original properties and reduces efficiency of oil filled equipment. In the most severe cases this will cause serious malfunctions, requiring long costly repairs.

Coming back to the issues of equipment downtime due to failures and repairs, let us refer to the statistics. Research shows that in similar situations in power plants (thermal and nuclear), turbine adjustment system failure rate has grown in recent decades, including failures of internal rotating part bearings. All of the cases were related to contamination of turbine oil.

The causes named above, after a look at power plant failure statistics, require efficient solutions.

The simplest and the most obvious solution is oil quality control and oil replacement. In practice this is, however, complicated, spawning several problems. First, complete removal of oil, sediment and other contaminants is impossible. Second, the disposal of used oil is a problem in itself. Constant disposal costs may eventually exceed estimated repairs cost.

The optimal solution, all things considered, is purification and regeneration of used turbine oil. Various types of mobile plants connected directly to the turbine assembly from which contaminated oil is drawn, removal gas and water, filter out solid particles and generally fully restore the oil to its original specifications.

For instance, the CMM mobile oil plants degas, remove contaminants and sediment from turbine oil. Among the advantages of these units is their capability to process the oil in one pass, significantly extending oil service life.

Depending on the needs of the facility, CMM plants may be either mobile or stationary. For larger facilities, CMM plants come with extra features, from additional filters to additional regeneration sections.

The main issues for any business are the possible profit and loss. The cost of regenerating 1 ton (depending on the type of purified, regenerated and lightened product) varies between US$6.5 to US$35. At the same time, disposal of industrial waste is a costly affair. Oil purification plants pay for themselves in a rather short time of 5 – 6 months at current prices.

Reincarnation of the hydraulic oil lifecycle

The lifecycle of hydraulic oil depends on several parameters which can extend or shorten the cycle. Some of these are viscosity, acidity and the amount of additives. Contaminating particles, free water, unfavorable operating conditions (temperature, loads and other conditions) all contribute to aging of oil.

Oxidation is further accelerated at temperatures exceeding 60C or in contact with some other materials. Presence of solid particles, especially larger than 2 micron, promote oxidation.

Contaminants are present in all hydraulic equipment. When the units are operated, friction causes additional solid particles and dust to enter the oil.

Therefore, to maintain high quality of oil and is operational parametes, it is important to protect its chemical composition, avoid overheating and protect the oil from water, minimize the amount of solid particles in the oil.

Oil filtration schedule is important to any industrial business. Filter efficiency depends on pore size. Large solid particles are retained by the filter as the oil passes through it, the smaller ones pass through the filter. Most modern filters successfully remove 1 – 5 micron particles.

Relative amount of solids increases as the size of the particles decreases. This means the oil will still be contaminated after filtration. The amount of contaminating particles will increase during operation and oxidation will be accelerated further.

Using the experience of many companies, it can be inferred that the dominating reason for malfunctions of hydraulic systems is related to contamination of the oil by solid particulate matter. Therefore it is extremely important to remove such contaminants.

As mentioned above, filtration alone is not enough. Microscopic particles pass through fine filters. Besides, water and air need other removal methods.

This is specifically what the UVR systems were designed for. Mobile or stationary design, direct connection to hydraulic systems for oil processing are just some of the features of this regeneration system.

Several filters, special pumps, heating and absorption allow removal of the smallest particles, as well as water and air from hydraulic oil. The sorbent media is can be reactivated shortly after running purification cycle is complete.

Oil purity regulations, savings on new resources and storage, unification of purification and filtration equipment are just some of the benefits of using the UVR type hydraulic oil purification system.
