Extend Transformer Oil Life and Improve Reliability

Our power transformer oil filtration systems simultaneously filter particulate and water contamination, extending transformer oil and component life, maintaining oil dielectric strength, and reducing the risk of electrical discharge and transformer failure. With over twenty filter options, SINFTFILTER can design a solution to meet your exact fluid cleanliness goals.

Transformer Oil Contamination Degrades Performance

Particle and water contamination reduce transformer oil dielectric strength and breakdown voltage, increasing the risk of electrical discharge and malfunction. Contamination also creates acid and sludge, lowering cooling efficiency and degrading transformer reliability.

Signs You Need Improved Filtration:

1. Reduced dielectric strength
2. Acid buildup from oxidation
3. Corona discharge and electrical arcing
4. Sludge on windings, reducing cooling effectiveness
5. Load Tap Changer contact wear and coking
6. Decreased transformer reliability
7. High oil disposal and replacement costs

Advanced Particulate Filtration

Particulate contamination constantly infiltrates transformer oil, even in new transformers and fresh oil. These particulates lower the oil’s dielectric strength, reduce reliability, and increase wear and coking of tap changer contacts. SINFTFILTER can filter particles to one micron, achieving any ISO cleanliness goal and:

1. Extend transformer oil life
2. Maintain fluid dielectric strength
3. Improve transformer reliability and minimize electrical discharge risk
4. Slow decomposition of paper insulation on windings
5. Reduce maintenance, downtime, and outages
6. Save on fluid disposal and replacement costs

Eliminate Water Contamination

Water enters transformer oil through humidity, poor seals, and during installation. It accelerates oxidation, acid buildup, varnish, and sludge, reducing cooling efficiency and increasing internal temperatures. Water also lowers the oil’s dielectric strength, raising the risk of electrical discharge and transformer failure. SINFTFILTER can:

1. Remove dissolved, emulsified, and free water
2. Minimize oxidation, acid buildup, varnish, and sludge
3. Extend transformer oil and component life
4. Maintain oil dielectric strength to reduce failures and downtime
5. Lower fluid disposal and replacement costs
