Transformers Online Dryout System (TODOS)

Description: Our Transformer Online Dry-Out System is a specialized device designed to continuously remove moisture from the insulation materials (oil and paper) of transformers while they remain in operation. Moisture accumulation within transformers poses a significant risk to their performance, as it reduces the dielectric strength of the insulation, accelerates aging, and increases the likelihood of electrical failures such as arcing or short circuits. The dry-out system mitigates these risks by maintaining low moisture levels, extending the life of the transformer, and improving its reliability.

The Transformer Online Dry-Out System works by circulating transformer oil through a drying unit. The oil passes through a specialized filter that captures moisture without interrupting transformer operation. Once the moisture is removed, the dry oil is returned to the transformer. This process is repeated continuously or periodically, depending on the system’s settings, ensuring the insulation remains dry and the transformer operates efficiently.

Operation: Initially, 

Key Objectives:

• Continuous Operation: The system operates while the transformer remains in service, eliminating the need for shutdowns during moisture removal.
• Moisture Removal: It extracts water from the transformer’s insulation materials, ensuring the dielectric strength of the transformer oil and paper is preserved.
• Real-Time Monitoring: Equipped with sensors and monitoring devices that track moisture content, temperature, and other key parameters to provide real-time feedback on the transformer’s condition.
• Self-Regulating: Some systems are self-regulating, automatically adjusting to changes in moisture levels and operating conditions to optimize drying efficiency.
• Compact and Efficient: The system is typically compact and can be installed directly on the transformer, often requiring minimal space and integrating smoothly into existing transformer setups.
