What details should be paid attention to when the transformer is operating under normal overload conditions?

Normally, the load of a transformer should not exceed its rated capacity. However, under certain special circumstances, it can operate with an overload within the specified range. The size and duration of the transformer's overload capacity are determined based on certain operating conditions (such as load changes, ambient medium temperature, etc.) and are related to the insulation aging of the transformer.

Please listen to the detailed explanation from the staff of Golden Eagle Coil. What should you pay attention to when a transformer is operating under normal overload conditions?

Transformers that operate at basically full capacity throughout the day should not be subjected to excessive overload.

2. During the 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 rate of the transformer is less than 1 during low-load periods, the allowable overloading multiple and duration of the transformer during peak load periods shall be determined based on the annual equivalent environmental temperature, load curve, and the load carried by the transformer before the overloading occurs.
