| Abstract: |
| Though recloser has had a universal application in rural power system,its application in urban power supply system is still on trial.The features of urban power supply system are introduced,including fault kinds and probability,momentary trip protection of substation circuit break,capacity ratings,loop scheme,demand for distribution automation,cable power system,etc.The application feasibility of recloser in urban power supply system and the difference between urban and rural power supply systems are discussed.It is proposed that recloser can be used in urban power supply system to improve the power supply reliability. |
| Key words: recloser,urban power system,loop scheme,cable power system |
