The line is long and there are many branches at the back end of the trunk line, most load of the whole line is concentrated on the branch line at the back end of the line. The length of the line makes the voltage more lower at the back end of the line, at the same time, there are a lot of loads at the back end of the line, the diameter of the transmission line is thin, which causes the voltage is more lower at the end of the line. Because of the impedance and inductive reactance in the transmission process, there will be a certain voltage drop in the transmission process. When the line is too long or the load is too heavy, the line voltage drop is large, the terminal voltage is low, even lower than the national standard limit, which seriously affects the users’ power consumption.
 
The series compensation device is installed on voltage 9.3kv which lower than the standard voltage, the voltage is 9.25kv and the terminal voltage is 8.4kv before putting into operation, the installation position voltage is 10.3kv and the terminal voltaeg is 9.32kv after putting into operation,which increased 1kV to meet the user's power quality with remarkable effect.
