Methods for selecting transformer capacity
When selecting distribution transformers in daily practice, choosing a capacity that’s too large can lead to the "overpowered engine pulling a light load" scenario. This not only increases equipment investment but also forces the transformer to operate continuously under no-load conditions, significantly boosting reactive power losses. On the other hand, selecting a transformer with insufficient capacity will result in the unit frequently running overloaded, greatly increasing the risk of overheating and even causing the transformer to burn out—this applies equally to both autotransformers and three-phase transformers. Therefore, accurately sizing transformer capacity is one of the key measures for reducing grid losses and saving energy. In practical applications, we can use the following simple method to determine the appropriate transformer capacity.

The operating environment of dry-type transformers
Avoid exposure to rain, moisture, high temperatures, intense heat, or direct sunlight. Ensure that the device's ventilation openings are kept at least 40 cm away from surrounding objects.

Structural Features of Dry-Type Transformers
Due to their strong short-circuit resistance, minimal maintenance requirements, high operational efficiency, compact size, and low noise levels, dry-type transformers are commonly used in environments with stringent fire- and explosion-proof performance demands.

The Development of Dry-Type Transformers
Since 1964, when Germany's AEG company developed the first 400 kVA / 20 kV epoxy-encapsulated dry-type transformer, dry transformers have entered a period of rapid growth. At the same time, the United States discovered Nomex insulation paper, which can be used as an insulating material for Class H dry transformers. As a result, today dry transformers fall into two main categories: one based on epoxy technology, and the other utilizing Nomex paper insulation.
