Substation Transformer - The Electricity Forum· Each transformer should withstand a certain amount of short-circuit load. However, the autotransformers for the underground substation in Shanghai can stand impedance of up to 22 percent. This means that the units will operate as usual even when exposed to a load 22 percent higher than their rated current. 4.
