Abstract :
The authors describe the functions and features of an automated distribution system which they have developed through studying and developing various types of distribution automation systems. This noninterruption system, with a high speed communication system and line sensors, significantly reduces both the time and the area affected by fault interruptions. The noninterruption system includes the following features: high performance, noninterruption on ground faults, quick isolation of short-circuit faulted sections, high reliability, easy expansion, and economy. These features exist thanks to the following components: multiplex master computer system, fiber optic communication system, optical line sensor, and SF6 gas switch. It is concluded that the noninterruption system provides power authorities with a means of significantly improving the quality of their power supply
