What Details Should Be Paid Attention To for Normal Overload of Transformers

What details should be paid attention to for normal overload of transformers

During normal operation, the load of a transformer should not exceed its rated capacity. However, under special circumstances, it can operate with overload within specified limits. The magnitude and duration of a transformer's overload capability are determined based on certain operating conditions (such as load changes, ambient medium temperature, etc.) and the insulation aging of the transformer.

Let's listen to the detailed explanation from the editor of Fuying Electronics on what should be noted for normal overload of transformers:

1. Transformers that are basically fully loaded throughout the day should not operate with heavy overload.

2. In summer, according to the typical load curve of the transformer, when its maximum load is lower than the rated capacity of the transformer.

3. When the load factor of the transformer is less than 1 during low-load periods, the allowable overload multiple and duration of the transformer during peak load periods are specified based on the annual equivalent ambient temperature, load curve, and the load carried by the transformer before overload, etc.
