Selection of load and transformer capacity in residential quarters Compared with residential areas in large and medium-sized cities, there are no high-rise buildings, elevators or central air conditioners in urban residential areas. Generally speaking, real estate developers only consider building houses and do not consider developing public utilities, such as schools and shopping malls. Therefore, urban residential quarters only have residential electricity, and load forecasting is relatively simple. -
Selection of distribution transformer capacity in industrial and mining enterprises The transformer operates most economically under the conditions of maximum efficiency and minimum loss, which is called economic operation. The actual capacity of the transformer, the production shift power supply system of industrial and mining enterprises, the nature of the power load, the load grade, the operation dispatching level, and even the local electricity price system are closely related. Especially under the condition of market economy, the selection of transformer capacity should be multifaceted -
Selection of load and transformer capacity in residential quarters Compared with residential quarters in large and medium-sized cities, there are no high-rise buildings, elevators or central air conditioners in urban residential quarters at present. Generally speaking, real estate developers only consider building houses and do not consider developing public utilities, such as schools and shopping malls. Therefore, urban residential quarters only have residential electricity, and load forecasting is relatively simple. -
