A transformer oil filtration machine is a specialized equipment used to purify and filter insulating oil in transformers. Transformer oil, also known as insulating oil, is crucial for the efficient operation and insulation of electrical transformers. Over time, transformer oil can become contaminated with moisture, dirt, and other impurities, which can degrade its performance and potentially damage the transformer.
Transformer oil filtration machines employ various techniques to remove impurities from the oil, such as:
The machine typically uses high-quality filters to physically remove solid particles, sludge, and other contaminants from the oil.
Some machines include degassing systems to remove dissolved gases, such as oxygen, nitrogen, and methane, which can degrade the insulating properties of the oil.
Moisture is a common contaminant in transformer oil and can lead to reduced dielectric strength. Transformer oil filtration machines often include dehydration systems, such as vacuum chambers or special absorbent materials, to remove water from the oil.
Heating the oil can help improve the efficiency of filtration and enhance the removal of contaminants.
By effectively removing impurities from transformer oil, filtration machines help extend the lifespan of transformers, improve their performance, and reduce the risk of equipment failure and downtime. Regular maintenance and filtration of transformer oil are essential for ensuring the reliability and safety of electrical power systems.
These type of transformer oil filtration & dehydration plants mainly used for filtration of distribution transformers. In these types, machine consists of single stage degassing chamber connected to single vacuum pump with high ultimate vacuum. From these machines, you will achieve the desired results within 3 to 5 passes of oil through the machine.
| SR NO. | PARAMETERS | INITIAL | FINAL |
|---|---|---|---|
| 1. | Brakdown Voltage with 2.5mm electrode Gap | 20Kv | 60kv |
| 2. | Moisture Content | 50-100 | Up to < 5-10 ppm |
| 3. | Particle Size | Visible to Naked eye | < 1 micron |
| 4. | Gas Content | < 10% by volume | upto < 0.1% by volume |
| 5. | Neutralization value(with IRC option only) | 0.5 mg of KOH/gm of oil | < 0.05mg of KOH/ gm of oil |
Two-stage degassing systems are designed for quickly filtering and drying transformer oil, especially in power transformers with minimal downtime and a need for fast results. These systems have two stages: the first stage connects to one vacuum pump, while the second stage connects to a combination of vacuum pumps called roots-rotary pumps. This setup creates a vacuum ranging from 0.1 to 0.2 mbar. By passing oil through the machine only 2 to 3 times, you can achieve the desired results.

A Transformer Oil Filtration and Dehydration Plant, also known as a Transformer Oil Purification Plant, is an advanced system designed to remove impurities and moisture from transformer oil, improving its dielectric strength and extending the lifespan of transformers. Here's how such a plant typically works:
1. Initial Inspection and Preparation: Before beginning the filtration and dehydration process, the transformer oil and the transformer itself are inspected to assess the level of contamination and moisture. The transformer may need to be disconnected from power and drained of its oil.
2.Oil Heating: The first step involves heating the transformer oil to a predetermined temperature. Heating the oil helps to reduce its viscosity, allowing contaminants and moisture to be more effectively removed during the filtration process.
3. Filtration: The heated oil is then pumped into the filtration system. The filtration system typically consists of several stages of filtration, including mechanical filters to remove solid particles, such as dirt and carbon, and chemical filters to remove dissolved impurities. These filters are designed to achieve a high level of oil purity.
4. Dehydration:gies such as vacuum dehydration or centrifugal dehydration to remove moisture from the oil. Moisture is a major cause of reduced dielectric strength in transformer oil, so removing it is critical for maintaining the insulation properties of the oil.
5. Degassing: In addition to moisture, dissolved gases such as oxygen, nitrogen, and methane can also degrade the performance of transformer oil. The purified and dehydrated oil is then subjected to a degassing process to remove these gases. This is often accomplished by exposing the oil to a high vacuum, causing the gases to vaporize and be removed from the oil.
6. Testing and Quality Control: Throughout the purification process, the quality of the oil is monitored using sensors and testing equipment. Parameters such as moisture content, dielectric strength, and gas content are measured to ensure that the oil meets specified standards.
7. Return to Transformer: Once the oil has been thoroughly purified, dehydrated, and degassed, it is pumped back into the transformer's reservoir. The transformer can then be refilled with the purified oil, and normal operation can resume.
Transformer Oil Filtration and Dehydration Plants are crucial for maintaining the reliability and efficiency of transformers, especially in high-voltage applications where the integrity of the insulation is critical. Regular maintenance with these plants helps to prevent equipment failure and extend the lifespan of transformers.
A transformer oil filtration machine is a crucial tool for maintaining the health and efficiency of transformers. However, for plants, especially industrial or manufacturing facilities, there are several other essential supplies and equipment needed to ensure smooth operations and safety. Here are some key items:
