- Deep Dehydration: The first-stage high vacuum (often below 1 mbar) effectively removes free and dissolved water to very low levels (e.g., <5 ppm), which is critical for maintaining dielectric strength.
- Thorough Degassing: Removes dissolved gases that cause oxidation, corona discharge, and reduce the insulating properties of the oil.
- Fine Particle Removal: The second-stage filtration, often using multiple filter cartridges to remove solid contaminants down to sub-micron levels (e.g., 1-3 µm).
- Restores Dielectric Strength: By removing water, gas, and particles, it dramatically improves the oil’s Breakdown Voltage (BDV), the key measure of insulating capability.
- Slows Oil Aging: Removing water and oxygen significantly inhibits oxidation and the formation of acids and sludge, extending the service life of both the oil and the transformer.
- Improves Cooling Efficiency: Clean, dry oil has better thermal conductivity, allowing the transformer to operate at optimal temperatures.
Maintenance of In-Service Transformers:
Preventive Maintenance: Regularly circulating transformer oil through a purifier removes by-products of normal operation (oxidation, slight arcing) before they can cause significant harm. This proactive approach extends the life of both the oil and the transformer itself.
On-Load Purification: Many modern purifiers can be connected to an energized (operating) transformer using a special safety system. This allows for oil purification to occur without any power outage, which is critical for facilities that cannot tolerate downtime.
Corrective Maintenance: If a transformer has experienced a fault, the oil can become heavily contaminated with carbon and gases. A purifier is used to quickly reclaim the oil and restore its properties, getting the transformer back into service.
