通常情况下， 加工 system of electrical equipment, generally divided into continuous operation, short-term operation, continuous short-term operation system, The principle of 加载 计算 is to replace the rated power of electrical equipment under different 加工 systems with the same long-term working system. The 计算 of distribution transformer load is a complicated process, therefore, it needs a lot of calculation and repeated verification by professional staff, in order to get the correct calculation results.
