What is transformer oil filter?
Regular transformer oil filtration assures long and consistent results from the transformer. Transformer oil purification is a process to remove sludge, dissolved moisture and dissolved gases from the oil. Transformer oil conditioning may also include to some extent improving the acidity of the oil.
What is the main purpose of transformer oil?
Transformer oil is used to insulate high-voltage electrical infrastructure such as transformers, capacitors, switches and circuit breakers. Transformer oils are designed to operate effectively at very high temperatures, cooling, insulating, and stopping corona discharges and arcing.
What is the effect of moisture in transformer oil?
Water is a threat to the insulation of oil (or ester) insulated power transformers. It leads to reduced breakdown strength of the oil and an accelerated aging of the cellulose insulation.
What is the purpose of placing transformer in oil filled tanks?
It is used in oil-filled transformers, some types of high-voltage capacitors, fluorescent lamp ballasts, and some types of high-voltage switches and circuit breakers. Its functions are to insulate, suppress corona discharge and arcing, and to serve as a coolant.
How does a transformer oil filter work?
Purification of the transformer oil by high vacuum transformer oil filtration machine removes all these contaminants from transformer oil. The dielectric strength of fresh, thoroughly purified (filtered, degassed, dehumidified) insulating oil is several times higher than that of aged, contaminated insulating oil.
What is process of oil filtration?
Filtration is a partial removal of solid particles through filter medium. Oil filtration systems generally use a multistage filtration with coarse and fine filters. Centrifugation is separation of oil and water, or oil and solid particles by centrifugal forces. Vacuum treatment degasses and dehydrates industrial oil.
What are the properties of good transformer oil?
The properties (or parameters) of transformer oil are:
- Electrical properties: Specific resistance, dielectric strength, dielectric dissipation factor.
- Chemical properties: Water content, acidity, sludge content.
- Physical properties: Interfacial tension, viscosity, flash point, pour point.
What is ppm in transformer oil?
PPM stands for Parts Per Million. It is used to measure the weight of moisture divided by the value of oil. The moisture content in oil lowers the insulating system dielectric strength that permits flashover to harm a transformer. For example, for mineral oil, a generally accepted maximum moisture content is 35 ppm.
Why is filtration and dehydration of transformer oil important?
Transformer Oil Filtration/Dehydration is an important part of regular transformer preventive maintenance. Our Transformer Oil Filtration Works are done with a vision to remove dissolved moisture, dirt, air and other gases from the transformer oil and winding.
What is transformer oil filtering and why is it important?
Hence, transformer oil filtering is an important process which eliminates solid particles, dissolved gasses, and dissolved water. The electrical properties of the oil can be enhanced by filtering, dehydration, and degassing. Oil Filtering keeps the transformer in good condition and increases its life.
How to treat and purify transformer oil?
In this procedure, insulating oil is tested and treated so that transformers will function efficiently. Dealing with transformer oil purification. To treat and purify insulating oil, transformer oil filtration process is required. Insulating oil filtration is a process of removing sludge and moisture from the transformer oil.
How to maintain the life of a transformer?
Transformer life mainly depends on the quality of oil volume it contains. Regular transformer oil filtration assures long and consistent results from the transformer. Transformer oil purification is a process to remove sludge, dissolved moisture and dissolved gases from the oil.
What is insulating oil filtration and why is it important?
Insulating oil filtration is a process of removing sludge and moisture from the transformer oil. Once the insulating oil fails to undergo this process, it can lead to:
