They play a crucial role in transmitting electrical energy from one point to another, transforming voltage levels, and maintaining the quality of the power supply. One of the most common types of transformers is the dry type transformer. In this article, we will explore what dry type transformers are, how they work, and their applications.
Because it does not use oil cooling, its heat dissipation process is simpler, and there is no need to worry about oil leakage or other safety issues. It is this simple heat dissipation method that makes dry-type transformers more reliable and environmentally friendly. What Are The Dry Type Transformer Types? Figure 3 Types of dry type transformer
Noise Reduction: Dry type transformers are quieter than oil-filled transformers because they do not contain oil, which can create noise and vibrations. Dry type transformers are an essential component of modern electrical systems.
Low-voltage dry-type transformers are designed for use in low-voltage distribution systems, typically up to 600 volts. They are commonly used in buildings, industrial facilities, and commercial installations. Medium-voltage dry-type transformers are designed for higher voltage levels, typically ranging from 601 volts to several thousand volts.
Disadvantages of Dry-Type Transformers: Limited Cooling Capacity: Dry-type transformers may have limited cooling capacity compared to oil-filled transformers. They may require forced air cooling systems, which can add to the cost and complexity of the installation.
Hospitals: Hospitals use dry type transformers to power their medical equipment and maintain a stable power supply. Renewable Energy: Dry type transformers are used in renewable energy systems such as wind turbines and solar power plants to convert the output voltage to the appropriate level for transmission.
