Demand Estimation for Sizing Distribution Transformers and Secondary Services in Rural Areas

Demand, energy con umption, and appliance data from 1156 rural consumers in 34 states were analyzed to determine coefficients of equations for predicting the 30-minute demands of individual consumers. Consumers in the South were found to have higher demands in relation to energy consumption than those in the North, and separate analyses were made for the two regions. The equations for predicting demand when used with appropriately programmed computers permit the automatic print-out of lists of consumers that may have overloaded transformers or services.
