Transformers are the heart of any electrical system, and insulating oil is a crucial factor in determining their performance and durability. Over time, however, insulating oil can become contaminated with impurities, moisture, or dissolved gases, reducing its dielectric properties and increasing the risk of failure. The Transformer Oil Filtration Service from KTH ELECTRIC provides an optimal solution to ensure your transformers operate efficiently and reliably.

Why Is Transformer Oil Filtration Necessary?

Insulating oil not only provides insulation but also cools transformers during operation. However, insulating oil is prone to aging and contamination, leading to serious issues:

• High water content: Reduces insulation capacity, increasing the risk of short circuits.
• Dissolved gases: Decreases insulation efficiency and raises operational temperatures.
• Impurities: Blocks oil flow, impacting cooling performance.

Without regular filtration, transformers can face severe failures, resulting in high repair or replacement costs.

Benefits of Regular Transformer Oil Filtration

1. Improves dielectric performance: Removes impurities and moisture, ensuring optimal insulation standards.
2. Extends equipment lifespan: Prevents damage and reduces component replacement costs.
3. Ensures safety: Avoids electrical failures that disrupt operations.
4. Cost savings: Regular maintenance minimizes risks and long-term operational costs.
