Outdoor pole type reactive compensation device has been widely promoted in 10 kV line power supply system

and the effects are obvious.In the operation of compensation device at 10 kV transmission and distribution line project

fault is happened due to improper design

which even causing capacitor damaged.The cause of fault is analyzed through analysis of electrical principle and system simulation

the problem in the application in the project is solved to achieve safe and reliable operation of the compensation device.According to practical application in the project

the design of reactive power compensation device for 10 kV line has been improved and the conclusion has been made

the important role of such compensation device is fully used.
