The output power of a dry-type transformer is a crucial characteristic that determines the speed of the transformer. So how can we accurately measure the output power of a dry-type transformer?   

The efficiency of a dry-type transformer can be measured using a power factor meter, but the maximum power cannot be determined. The rated power is clearly specified by its construction and can be found on the factory nameplate of the dry-type transformer. If the maximum power cannot be determined, I will introduce a method for you:

Generally, it involves connecting the dry-type transformer to the necessary output power load, accurately measuring whether the operating voltage meets the requirements, and checking the heating condition. If the operating voltage meets the specifications and the long-term ambient temperature is not too high, it can be used.
