Introduction: the average load factor of the load curve is higher, the loss of power to achieve smaller loss than to use smaller transformers load curve of the average load factor is low, the loss of power to achieve smaller transformers, the greater the loss ratio to use. The average load factor of the load curve is multiplied by a factor of more than 1, usually desirable 1-1.3, as the best efficiency of the load factor, and then according to the beta B (1/R) 1/2 calculation of the transformer should have the loss ratio.
