Xi’an Jiaotong University Xi’an 710049 China ) Abstract In recent years, some new sensor technologies for pressure, thermal energy and arc light sensors have been applied in online detecting sys/doc/34fd05e0e009581b6bd9ebc0.htmltem for internal faults arc. But most of these methods are too complicated and expensive to be used widely. many kinds of lights, such as corona, surface sparkle, sunlight, lamp light, electric torch light as well as arc light, are researched. The characteristic of arc light is found via a series of light sense tests, therefore the single criterion of arc is adopted. On this basis, an optic fiber sensor for arc light is developed. Finally, a practical multi-point distributed online detecting and protection system for internal faults arc is researched and developed. This system is economic with simple construction, high anti-jamming capacity and very short action time; it can not only be used separately, but also be integrated with various existing digital relay protection systems, therefore the technology level and added value of switchgear can be enhanced while the cost only increases a little.
