Transformers are crucial components of the electrical transmission and distribution network. Their main role is to raise or lower voltage levels to ensure efficient electricity delivery. However, like all equipment, transformers face wear and tear, often caused by moisture buildup or oil contamination over time. This is where Minimac Systems' Transformer Dry-Out Systems (TDOS) play a vital role.
The transformer is the heart of the power circulation system. To maintain the transformer to its peak performance, high purity of insulating oil is very important. Excessive moisture in transformer oil significantly reduces the dielectric strength of the transformer oil. To maintain the moisture-free insulation papers in the transformer, a designed transformer dry-out system can play a decisive role.
TDOS is an online dry-out kidney loop system and can be easily connected to a charged transformer for drying out the transformer. It works on the principle of moisture absorption. Oil passes through the series of inline moisture absorption cartridges, where moisture gets absorbed and moisture-free oil returns to the transformer. The TDOS equipment with the moisture sensors at the inlet and outlet provides automation to regulate the process; when inlet oil moisture reaches the desired level, the machine will automatically stop. Also, the machine is designed with interlocks to protect the transformer's safety.
The system is capable of removing the water contamination from the oil of more than 5% to less than 0.01% in a short time.

Enhanced Performance:Moisture can damage a transformer’s insulation, leading to dielectric breakdown and partial discharge. Removing this moisture helps the transformer operate at peak efficiency.
Increased Longevity:The less moisture present in the insulation, the slower the aging process, which helps extend the transformer's life.
Safety:High moisture levels can cause electrical shorts, sparking, and safety hazards.
Cost Savings: Preventing moisture-related failures reduces maintenance costs and avoids costly downtime.
Filtration Unit:Removes solid contaminants from the oil with high-efficiency filters.
Advanced Dehydration Technology:Uses vacuum dehydration, molecular sieves, or a combination to remove moisture effectively.
Heating Unit:Gradually heat the oil to help remove moisture.
Control Panel:Allows users to monitor and control the system's parameters for safe and efficient drying.
Compatibility:Ensure the oil in the transformer matches the system.
Capacity:Choose a system that can handle the oil volume.
Automation: Opt for systems with automatic features for easy operation.
Maintenance:Look for easy-to-maintain systems.
