 How to choose the model and specification of oil-immersed three-phase distribution transformer according to load capacity?

Selecting a Transformer Based on Load Capacity：

Calculate Total Load Power：

• First, it is necessary to determine the total power of the loads to be supplied. For residential areas, this involves considering the total power of all household electrical appliances, including lighting fixtures, televisions, refrigerators, air conditioners, etc. For example, in a residential area with 100 households, if the average power consumption per household is 5 kW (considering the simultaneous use factor), the total load power would be approximately 500 kW.

• In industrial settings, it is necessary to tally the power of all production equipment, lighting, and office devices within the factory. For instance, in a small mechanical processing plant, the total power of machine tools might be 300 kW, and adding the power of lighting and office devices, the total load power could reach around 350 kW.

Consider Simultaneous Factor and Power Factor：

• The simultaneous factor refers to the probability that all loads will operate simultaneously at any given moment. In residential areas, the simultaneous factor is generally between 0.4 and 0.6. In industrial settings, it is determined based on production shifts and equipment operating patterns, typically ranging from 0.7 to 0.9.

• The power factor reflects the efficiency of energy utilization by the load. In scenarios with a high proportion of inductive loads (such as motors), the power factor is lower, usually between 0.7 and 0.9. It is essential to calculate based on actual load conditions and then select the transformer capacity based on the calculated actual load capacity.
