The invention discloses an intelligent transformer which comprises a transformer body and a monitoring terminal. A voltage regulating switch, a capacitance regulating switch and a load control switch are arranged in the transformer body, the capacitance regulating switch is connected with a capacitance regulating controller through a circuit, and the monitoring terminal is connected with the voltage regulating switch, the capacitance regulating switch, the load control switch and a wireless communication module through circuits. The intelligent transformer realizes remote controllability and automatic capacitance and voltage regulation, reactive compensation distribution reasonability is achieved on the whole network of an electric power system, optimized reactive flowing is achieved, and therefore power distribution energy consumption is lowered.
