Transformers are a common and useful device that receives high voltage directly from a power station and converts it to a lower voltage. This enables safe and efficient use of machines and equipment that can handle low voltages in spaces such as offices, transportation hubs, schools and factories to save energy.

Through this process, the transformer generates a large amount of heat that must be dissipated to maintain safe operation. There are two types of transformers currently used in the industry: dry type transformers and oil immersed power transformer. Dry air is used as the cooling medium, and liquid cooling is used as the oil. Although both types have the same end result, it's worth noting that there are many differences between them that will affect the type you choose.

Maintenance: Oil immersed power transformers require more maintenance procedures and must be executed more frequently than dry. Oil needs to be sampled to test for contamination, while dry type transformers are highly resistant to chemical contaminants.

Cost (initial and running): Dry type transformer has significantly higher operating losses compared to oil immersion. Oil filled transformers have a higher standard energy efficiency and therefore have a higher service life than dry type transformers.

Noise: Oil immersed power transformers operate at lower sound levels, so noise pollution is lower than dry.

Recyclability: The life cycle of dry recycling is limited, while the core/coil recovery of petroleum plants is easier. Oil immersed power transformer has superior service life and maintainability, produces less waste, and requires less replacement and labor.

Efficiency: Dry type transformers are larger units with limited voltage and size. If they experience overload, they are more likely to overheat. As a result, they have higher electrical losses and it is more expensive to maintain dry power over time. Oil-cooled units are smaller and more efficient. They have less demand and a smaller environmental footprint.

Voltage Capability: Dry type transformers are designed to handle small to medium MVA and rated voltages, making them ideal for small applications. Oil immersed power transformers can withstand heavier loads, so applications that require higher voltages will require oil units.

Location: The location of the transformer will be the biggest determinant of which type you need. Dry design is used near buildings and buildings simply because they are safer for the environment. Dry type transformers are less flammable and less risky to fire, making them ideal for shopping malls, hospitals, residential areas and other commercial areas. Oil immersed power transformers are used for outdoor installations because there may be oil spills, which pose a fire hazard, but these devices are more environmentally friendly.

Taking into account these variables, petroleum plants appear to be a better choice, with higher energy efficiency, recyclability, low noise pollution, lower operating costs and a small environmental footprint. However, petroleum equipment cannot be used at all under any circumstances. Dry type transformers are the best and multiple must-have option for commercial and indoor operations because they are safer units that operate around people and areas where fire hazards may exist.
