What is the difference between intelligent box substation and ordinary box substation?

At present, the domestic intelligent box-type substation is the mode of traditional box-type transformer+intelligent unit. The intelligent unit is responsible for collecting voltage, current, temperature and humidity, switch position and other signals in the box transformer, and transmitting them to the remote monitoring center through communication. At the same time, the intelligent unit also has remote control function. To put it simply, the intelligent box has four or five more remote communication functions (remote communication, telemetry, remote control, remote adjustment and remote pulse) than the traditional box transformer.
